After talking with Valerie and Andreas on the Volunteer Chat and also with Matthias, who is working on the design of the BW forum, I think it is about time to involve some more users in the brainstorming about how our forum should look like.
There was a consensus so far that the tag system has some great potential, but does not really make it easier for users to get into the forum system. For that we should have more of the fixed categories.
In the long run I personally would love to see Categories and Subcategories that users can but needn't expand (this is called Accordion-effect, I have been told, and mostly you will find this system when you organize your folders with main and sub-folders) So a sports category could be expanded and reveal Football, Hiking, Canoeing, Biking. The system should remember whether a user wants to have some categories expanded by default or not.
Also in the long run it would be great to have different possibilities of sorting the tags: alphabetical, most popular, most recent, my favourites, etc.
In the short run we should just have a longer list of categories.
Suggestions that have come up:
*Music (this would logically later be a subcategory of the first)
I also think that the list of recent posts should be shorter (5?)
Please give some feedback here and especially contribute to the list of categories - Matthias is actually waiting to implement it.
