Too much to read, sorry. Maybe there is nothing new in my first impressions:
- Header looks deserted. I would expect some kind of breadcrumb, and some default text next to the icon.
- Welcome message contains the link “Open Source Design (forum)” but shows the external site in the same window. Better we open a new tab.
- Start page throws all (new?) threads in my face. Way too many information with all the avatars. If we start with categories in h1 and some descriptive text it helps to understand what users are supposed to do here.
- Wonder if replies are always just added to the time line or if there is a thread option. Otherwise we quickly run into trouble with lengthy discussions.
Great work anyway! A lot of cool helper tools :-).
