Thank you, Hoj! Means a lot coming from you.
Believe me, this place has been a Joomla website up until about three weeks ago. Figured some extra content besides the forum would be wonderful. Bad decision, at least for me. I intended it to be quite versatile and complete with all manner of gadgets that Joomla plugins could provide, yet it turned out that it was rather poor in both loading speed and pagination. Mobile device users had a hard time loading and reading anything on it. The Kunena forum designed for Joomla was not that shiny a piece of work and was merely ok. Probably even drove some people off or made them reluctant to post for some time.
In other words, for all the hype around its status as "free" software, Joomla seems ok only if you're willing to spend a decent amount of coin optimising your site, buying full versions of various plugins and generally have someone fit everything together.
PhpBB seems to do the job neatly, since most of the activity was on the forum anyway. Besides, a couple of plugins built for phpBB seem to make up for any special needs that might arise. Like the classifieds section or the blog-articles section. And the forum itself is a tried and tested piece of software (if generally horrible with plugins), no need to go complicated if simple does the job.
What we do lack is - as a fellow member put it - an USP, something to really make the place shine. A definite identity of our own, if you will. Still have to sort that out.
