Multiple or grouped single account?
 

For the experienced TGP'ers...

Let's say I have DOMAIN1, DOMAIN2, DOMAIN3, DOMAIN4, etc... and I have my own server... Should I create a new account for each domain or group them all under one account?

Personally I find it easier to create a new account for each domain, but what does everyone else do and why?

PS: I have AGSQL and a few sites grouped under one domain but it's confusing as heck :( I'm going to create a whole whack of TGP's with Vanilla now and want to do it right the first time.
