[mini2]

It's basically done, although I'm not sure I'll use it now! Still might.

The only catch I've encountered (and I will try and work this out probably later this week) is this.

I sign up and use domain1.com, I surf it, post on it, join in on it all fine. Everything I do is reflected on domain2.com, and everything there is reflected on domain1.com.

I've managed (although it took a bit of manual tinkering) to allow different names etc. too, even for forums and categories.

The ONLY issue I've encountered which gives the game away to the user is that private message and subscription notifications are always sent from the domain the private message or new post is posted to. I.e. a user of domain1.com gets sent a PM from a user on domain2.com, the email comes from domain2.com. The same on email notifications.
