Although I still feel I have a lot of tweaking to do, I'm ready to get some peer feedback on my first Drupal website.
Bikes on Show (http://bikesonshow.com) has been around for 4-5 years as a PHPBB Plus portal/forum website, but I got stuck trying to upgrade to PHPBB3 so I decided to look for another platform - and Drupal looked like a good choice.
At first I thought I'd just integrate PHPBB3 into Drupal, but there were too many things I could not do using that model. So I converted the forums from PHPPB2 to PHPBB3 first, then used the 6.x version of the PHPBB conversion module to move them across to Drupal forums. I am still tidying up things like BBCODE and broken links in the forum topics, but mostly they are OK. I found that the forum redirection module did nothing for me, so I am writing my own redirections for each major PHPBB function.
The theme is a variation on FeverUltra, which was developed for the World Cup. I liked the way it uses views to rotate featured content on the home page, and it was also one of the very few themes I could find that has advanced forum support.
