Topic: Ordbok forums
My forum has already been running for a while; time to announce it here. :)
The site is for Dutch people learning Swedish and the other way around. I made some modifications to the php code, so I hope that when punbb 1.3 is released, it won't have too many nice new features, because that would mean I have to backport a few things.
* Style sheets (in the colors of the Swedish flag); other layout for avatars
* List of active topics
* Auto-sensing the preferred language for guests (Swedish or Dutch; Gecko (Mozilla/Firefox/etc) and Opera users that don't have selected Swedish or Dutch in their browsers will get English.
* Captcha for guest posts and new registrations. I designed the Captcha after reading some papers about how captchas can be defeated. This one should be pretty tough for OCR algorithms.
* Posts can only be modified within 7 days after posting; within the first 30 minutes, there won't be a 'last modified' message.
* Quote length limiter. Posts are refused if more than about 50% of the message consists of quotes. (That needed some finetuning to deal with quotes containing lots of short lines)
* rel="nofollow" in links to pages that shouldn't be indexed by search engines (user info and such). Although these pages contain a meta robots tag, I've also put them into robots.txt, which means that google doesn't fetch the pages, but their URLs will still show up on Google if there's any page linking to them.
* The admin account gets to see the last visit date in the user list.
