I know. But i have seen a lot of forums with phpbb 3 software before the used phpbb2. And I want to test the functions. But i wil kept the 100 messages and 5 users.
You can download the beta and try it out but the convertor from phpbb2 is not ready yet.
People running it live have either not read the warnings that they will not be able to upgrade or they are very experienced programmers who can upgrade it themself.
-:|:- Support Request Template -:|:- "Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb"
then setup a sub forum, or rename the phpbb3 folder into something like phpbb3test and create a new DB, don't bother to use a phpbb2 one at this time, then you can use phpbb3 beta or a recent CVS (unsupported) for testing purposes only
but if you do try to convert a phpbb2 forum, as it has been stated its unsupported and you will be on your own, plus the DB I doubt will be upgradeable to final anyway so you would have lost all that data,
so you can still use phpbb3 as long as its for your own use and not a live board
