To continue the discussion of punbb compared to others, I too am a huge disciple of punbb - having discovered it when I was looking for a forum solution for my neighborhood website that I maintain for the fun of it.
I have a personal website (to share news and pictures of my kids with my parents who live in another country) which runs entirely on PHPBBFM, or Fully Modded PHP. the sad thing about it is the much embattled "owner" of the heavily modded board has a problem. His host closed up shop and with it took his website offline. Of course (predictably) there were no backups, so the support site, for what it was worth, has disappeared from http://phpbbfm.net
Forum membership and support were paid for, so there are a lot of us out there who are now not getting the support and product we paid for. It seemed though for a while that support and subscription for the product was dwindling due to many reasons - the installation with it's many mods simply grew too big, slow, and resource hungry. At times too, support on the site was non-existent, and requests for help were ignored, complaints deleted...the list goes on.
Further, when logging into my admin panel for my site, I have to wait for an eternity while the software tries in vain to check the software version against a non-existent server.
I keep using the forum software out of posterity I guess, but punbb really gets my vote. Preaching to the choir though, right ?
Oh, and trying to interpret this thread's title has given me a headache.
