Looks great! I'd suggest slightly changing one of the blue colors, it's very hard to see things like the breadcrumb. Is the number to the left the amount of new posts, or total posts in that forum? Cool idea, I haven't seen anyone do that before.

If you're wanting to actually release this someday, please please please do not use tables as your main content structure. A default responsive theme isn't necessary but building the forum on tables makes it extremely difficult and time consuming for designers to remove them. Even if it means using something like bootstrap to get the main content structure. This doesn't mean you can't use tables in the correct places.

Great works so far, surprised to see so much progress. Good luck!
