Ok, here's a little update on the status.
Work on the site is almost done.
The article system works, all files from the old support site have moved to the new one and the file tagging is done, too. Now I still need to move/rewrite the articles, which is quite a task, since Keltic Danor had put much effort into that when he made the first site.
I kicked Download counting in favor of ease of use and direct linking, which is a pain when you have one of these "wait a few seconds while I passively activate the download" sites. And honestly, who's really interested in how many people have downloaded your stuff? There's a commenting/rating function for every file and article. IMO that's enough to give people an impression over the popularity of a certain file or article. If someone writes crap, it can be removed/edited very easily with the admin panel, anyway.
There's no bug reporting system YET, but it can be added afterwards easily.
Thanks for your input, people!
