I've used the the view method suggested in the past by Sir Adrian.

The only issue I had was with PM's since we wanted to keep them separate between the forums, and the user table stored the stats for that. So now I'm working on that issue.

if you had the sites on the same hosting. couldn't you make cookies sub-domain based? and treat the other site as the same session? also, i notice you can't pm members or the avatars aren't carrying over. and its db based file storage

Thanks for this hack.

Ok, I guess this should work if avatars are stored in the database instead of files, but for some reason, in User CP, 'Do not use an avatar' is checked instead of 'Use Custom Avatar.' Which table holds that setting?

ETA: Ok, found it -- just add the 'customavatar' table to the list.

Ok, I have a quick question, I have a old user back up from a forum I had a year ago, can I use this to revert data bases in a way I can use the old emails to the new forum?

Can I do this?

Hmm, for some reason, I can't perform searches... It always returns 'no matches'...

Anyone make this work when your board does not use a pfefix for you database?

You can go without prefix on your main database (where users lie), changing to: $main_prefix = "";

but the new forums that you add, which will use the main user database should have prefixes, and should be new forums, you cannot join old forums with their own user databases.

Uhh, I have to check that.

For me it's working:

If I search here for "pruebecita" it works

this forum is using the user database from:

http://www.foropymes.es/foro/

Could you give some details of your problem?

I got it up and running and every thing seems to function perfect besides one thing.

I store my avatars on disk (file system) instead of the database storage. Anyone know how to properly link this? I am scratching my head on this, as avatars do not show up.

Store the avatars back to the database and add 'customavatar' to the list.
