is MYsql 5.0 really required?

If your version of MySQL doesn't support sub-queries you will not be able to use organic group forums and regular forums at the same time.

I am not a db wiz, but need og forums, it is required to get TAC and og user roles to play nicely. I am limited to using mysql v4, no option for v5 presently. but I did find this however, "As of version 4.1 of MySQL, however, sub-queries are now possible. This month, I will explore how to use sub-queries in MySQL."

sorry to post again, but this is from the mysql manual:

If it works, then it works, but using MySQL 5 is a safe bet. Sometimes early implementations of things aren't as refined as later versions - i.e. bugs get fixed. I'm not aware of any bugs in your version, but I don't follow that sort of thing. I have noticed several functions which were incorrectly implemented prior to version 5.1, for example, but I don't recall whether those have anything to do with this or not. We list the requirement because that's what we use and unless people submit patches for earlier versions, we won't intentionally support 4.x.

That should answer your question, right?

yes, thank you.
