For the integration mods that were released with INdexU Deluxe v1.1 some users had some questions. I found out the the answers and am posting them here

1) Do the databases have to be on the same server?
Yes

2) What happens with existing IndexU usernames?
They are ignored, so a user may need to sign up again on an already existing site.

3) Lets use vbulletin integration as an example. If a user registers in vbulletin first, then logs into vbulletin, and if they want to log into IndexU they have to log into IndexU seperately correct?
Yes, but a user does NOT need to log into vbulletin first. As long as they have a valid login they may login to either program.
