Just to note, a post count should be just that: a post count; not a post count minus this one particular forum. Maybe have two post counts: one post count with all RR Forum posts (total) and one with all posts minus the RR Tavern Forum. Possibly in the format with the total count as it currently is displayed and the one without the RR Tavern in parenthesis (e.g. "Posts: 877 (777)"). This way, all can see the comparison. In the example, you can see that 100 posts were in the RR Tavern.
As to the inability to search for words/phrases in the RR Tavern Forum, I would prefer to be able to search for all items on RR. I was just searching for something I read in the RR Tavern the other day to help me out with something I was working on. Without this tool (search entire RR site), I would not have been able to do this.
However, if there is some particular substantial reason for eliminating the global search (to include the RR Tavern Forum) and it is of benefit to all the members, then I suppose we could do without this tool. Note that I see it as a "tool" and not a feature.
