Re: Icy Phoenix 1.2.18.45 Beta 1
-----------------------------------
[quote user="Greg Verso" post="36199"]a month ago i make a trial forum with Icy Phoenix.
Just to learn it before put it to the main site.
now i have to install it again but i don't care because i'm sure that this one is much better than the old one.

and know one question.
the new one (beta1) is it based on phpbb2 or on phpbb3 ?
sorry but my English are not to good.
i read it some times but............. :(  :(  :([/quote]

phpBB2.  It's nearly a hybrid if you think about it though. :)

Either way, Icy Phoenix > phpBB3.
