For those having trouble -- OBVIOUSLY you modify the new code around your existing hacks. Someone (I take it?) says that the contract/expand hack doesn't work? It did on my board -- I just had to re-insert the mods into the templates again.
I keep full records of EVERY modification I make to the board on my site, the forums are what make my site and I reeeeeeally don't want them screwed up for long if I can help it.
When I was installing 2.2.2 I didn't even have to turn the board off, users didn't even know I'd upgraded -- but I haven't had a single 'my link in e-mail doesn't work' e-mail.
I'd just like to thank 'PPN' again for taking the time to do this.
