Change wording of group nav buttons
"The Groups Tab a the top of COMMONS-02.pdf is plural and brings you
the Groups Directory page. The Forum button in the sidebar of that page
is singular and brings you to a Group's Forums Directory. Making the
"Fourm" button "Forums" seems to make it a bit more symmetric with
the "Groups" button and eliminates the need for the Group Forum button
under the Forum title."
Personally, I disagree with this. That's partly because, in BuddyPress terminology, 'forums' are one-per-group, and are made up of topics (which are, in turn, made up of posts). Groups don't have multiple forums, they have a single forum with multiple topics. This is largely semantic and there is perhaps not a great argument for one option over another; however, I do think we should be internally consistent, and elsewhere, we use the forum/topic/post terminology.
However, I do think it's a good idea to get rid of the Group Forum button, or to change it to something a bit clearer, like "See all of [group]'s topics".
