This works with cookies. If you have the IP Address Prevention, it should catch it, but if not, cookies will not carry through different browsers. Also, make sure you don't have your Admin account ignored.

The difference is the new and improved features, as well as faster, more efficient code.

Funny you should mention that, I actually thought that I did, but it appears that I only have it on my server... Apparently I forgot to package it. I'll reupload the package with a blank index.html. Of course, the version will remain the same.

Excuse me? I do not see any errors in that. If you removed the URL tags, that's modifying my modification, and then that's not my fault. If you keep the URL tags in there, it should display just fine. The & string is the correct way to link anything with & in it - it doesn't break anything. Also, there's no reason to not link to the member info - it just makes things easier.

real? an empty index.html can protect me?

You don't get it. I removed the url-tags, otherwise you won't see that piece of code in my reply. I left it the way it was in the phrase.
Point is, the & is not being parsed. In other words, the link that'll show up in the message or pm will be:
http://www.forum.com/member.php?do=g...p;username=ray instead of http://www.forum.com/member.php?do=getinfo&username=ray

Not clear enough? Here's how it would be on vb.org:
https://vborg.vbsupport.ru/member.ph...;username=ray-

Doesn't work, because the "&" isn't parsed.
What does work is:
https://vborg.vbsupport.ru/member.ph...&username=ray-

I have Multiple account login detector (AE Detector) installed.
https://vborg.vbsupport.ru/showthread.php?t=183268
Is this an upgrade for that or a completely different installation?

An empty index.html will just ensure that the files are not listed in the /madp/ folder. Nothing bad can come from someone knowing of the files in this folder, but it allows there to be a blank page instead of showing specific files.

Apparently, we are both right. & is a correct and standard entity, however, it seems that the '&' in '&' is being parsed, so it's turning out to be &.

The & entity is a standard - just like &nsbp; and © - but since this is affecting some browsers like Opera, I'll try it with a blank & in hopes that it will be correctly parsed into &.

Thank you for bringing this up.

This is a completely different modification. You should uninstall the "Multiple account login detector (AE Detector)" and "Multiple Account Registration Prevention" before installing this modification.

OK thank you very much for response.

Great job ..... ANd thanks ,,

sorry my bad,
lets say that alessai1 and alessai2 are sharing the same computer

when i open alessai1 profile it will be great if there is a tab (anything else is fine) that shows alessai2 is sharing the computer with alessai1.....

when i want to give alessai1 infraction a note appears, that tell me alessai2 is sharing the computer with alessai1

another idea (dont really need it) if alessai1 and alessai2 posted in the same thread, a small icon appears on alessai1 postbit that takes you to alessai2 post (and same apply to alessai2 post).

those ideas will make our life much easier because to me right now the addon is useless because i have a big forum, and i cant prevent every one and cant check every thread created by the addon

I'm truly sorry, but at this time, I do not think I'll be able to add that. A few reasons: I would like this modification to remain as compatible as possible with previous versions, and there are major profile differences between vBulletin 3.6.x and vBulletin 3.7.x; also, such a feature would require a database table, and I don't want to get into database work if the modification doesn't require it to function properly; and finally, I wouldn't know where to begin with the install/uninstall code for a database-involved modification.

Maybe in time, if I learn more about the differences in vBulletin versions, install/uninstall code for database tables, and SQL, itself. For now, though, my only suggestion is to let the modification prevent multiple registrants, and then prune the multiple accounts on a weekly basis by going to the AdmcinCP home, clicking [View] next to 'Users to Moderate' near the top, and deleting all of them. That should work out nicely as long as you have the Prevention Usergroup set to 4 (Users Awaiting Moderation).

Again, I'm sorry that I cannot add in those features at this time =/

On a brighter note, I'm about to release version 1.0.2, which has a few improvements, a fix for the & interpretation that 'ray-' brought up, and an added feature (Ignored ISPs).

Alright, version 1.0.2 has been released.

The Ignored ISPs feature has not been sufficiently tested, so while I will continue testing it on my forums, I would like feedback on this somewhat-beta feature.

I'll try to have version 1.0.3 out as soon as possible, which will enable administrators to have a custom name for the cookie instead of just IDstack.

Edit:

I have just finished up version 1.0.3 and I plan to release it later today - after a good bit of testing.
