Well.. You are right, but there are also other things that come in to play..

There are -some- set backs to using mod_perl (like if your code isn't written with mod_perl in mind it might not run as expected.. global vars stay in memory etc.. was wwwthreads writen to take mod_perl into account?)

You have to also remember that some people who have the ability to run PHP might not have the ability to run Perl (don't ask me why, but I'm sure this is true for somebody out there)

I do remember reading through wwwthreads source and seeing comments like "this feature doesn't work under mod_perl" etc...

Also I think that if wwwthreads was written in PHP it would make it 10x easier to hack the layout of your forum..

Since PHP is embeded into HTML like ASP it keeps the HTML code cleaner looking and easier to change where as perl the HTML code usually looks very ugly....

Once again.. Don't get me wrong.. I love perl.. I write perl for a living..

Oh and about the UBB comment... I agree.. try vbulletin <A HREF="http://www.vbulletin.com" target="_new">http://www.vbulletin.com</A> it's not as good as wwwthreads, but it's a decent php forum that copies UBB's style (I hate not having threaded view though)
