No, I'm not (yet) using Icy Phoenix, but still using phpbb 2.0.22. Never wanted to migrate to phpbb 3 since I had several mods that made my forum almost completely spam free. Just discovered Icy Phoenix, sounds interesting, but have to discover more of it to see if I want to migrate.
And no, the code isn't already there, otherwise I wouldn't need this mod.
On the other hand, I'm a bit confused about the version I'm using. As far as I'm aware of, I'm using the Clown version of Smartors Album. Downloaded it most probably early 2007 from phpbbhacks.com at a time smartors site was down.
