I never said it cant be done
. I only said it cant be done with just changing the some table names. There need to be changed a lot more things.
Sorry, I didn't mean to say that you said it can't be done, I did test it with multible forums (3) on my local computer. Only sharing users database. I see some problems with the Avatars, However, I didn't set it up on a full production web site. There might be some other problems I didn't see.
I remember that discussion (the above link). I thought it was longer than it showed. oh well.
Hmmm now you have me curious. I might set up one to see how it goes and what problems that might be encountered. I know this question has come up before..
