Yes, it would only affect new user registrations. Worst case would be that two users get the same Wiki account.
e.g:
VB username 1: "test_test"
VB username 2: "test test"
Both would use the "Test test" wiki user account, because all '_' will be converted to ' '.

For tests I created an user "_test : ? ^ & ( ) *" in VB, even there the user was able to use the wiki with this username: "Test : ? ^ & ( ) *" and the userpage was: "User:Test_:_%3F_^_%26_(_)_*"
As you see the first char should not be an '_' or an ' ' else it just gets removed, the other chars did not really make a problem.

I need to do some more tests to see what chars we really need to disallow.

Thank you for the info. I did a bit of digging as well and found out that the characters forbidden in a username are the same as those that are forbidden in a page title. There is an article that talks about that here.

I hope that helps a little bit. Based on that I think you should be able to get a regex that should work for just about everyone.

With this new mod, are the users in the MediaWiki table ignored? My users are getting login errors on the old product, and I was looking for a way to delete them out of the MW user tables, but if this mod solves that, I'll uninstall the old mod and install this one. Thanks for any advice.

Yes, I've read that page, but not all the page title restrictions are needed for the user.
I've come up with this now:
[^_ #:~\/[\]]{1} -> for avoiding space as first char
_ -> would be converted to a space in the username
# -> Wiki does not allow it
: -> someone might use a username like 'Talk:ToMe' ... that would be a Wiki Namespace
~ -> Wiki does not allow this sequence: '~~~'
/ -> Name is used in the URL, so we cannot have users with something like "../" or "./" or "/../" in the name... so disallow the '/' or the '.'
[] -> Wiki does not allow it

I did some changes to the login stuff... but even with the old version there should not have been problems if an user name exists in the Wiki User DB already... this mod will just use the existing Wiki user if the VB user exists in the wiki DB already

Can you tell me exactly what username is making the problems? (vb and the one that is in the wiki)

I need to recreate the problem or you send me a link to your forum with one of this accounts that is have problems... I need to look into that

Everything seems to working more or less ok.

Couple of things:
1) The nav bar shows a blank tab, instead of Wiki or whatever I've defined as mediawiki_name in Phrases.

2) It seems to have some issues with my website when displaying integrated, such as Chat box EVO loading for enternity.

My site is www.houseofkarrdes.com - Wiki is visible to guests.

EDIT: Also, the sub-nav bar shows: {wiki:raw personal_urls}, which I'm assuming is where things like the user's wiki preferences are supposed to be.

I should've looked, I've started from scratch with 1.16 since I'd deleted some users out of the previous versions user table before I realized how bad that was. I've installed the new version on top of 1.16 and I don't see Wiki in the tab either.

oh, and the subtab text is black on only contains "{wiki:raw personal_urls} "

Also, for some reason although I am a vb Administrator, and I have the sysop and beaurocrat setting for admins set to use, I don't get the edit option.

The old templates did not get overwritten...
- Did you uninstall the old version before installing the new one?
- Did you edid some of the vbMediaWiki templates before installing?
