Thanks for this hint, Derek. I didn't follow-up because I don't think a
free-tagging vocab will help us here. IMHO, we need something we can put in
the visible navigation for d.o users. Yes, free tags are not limited to a
few terms. However, because of that, it's harder to build a fixed list of
issue topics based on them.

Though the title of the issue Derek linked to above mentions free tagging, this could also be done with fixed vocabularies. For an example of how this might look, see the first screenshot posted at http://drupal.org/node/187480#comment-632130. Both of these vocabularies are free tagging, but fixed vocabularies would look similar.

The comment_alter_taxonomy module that I will finish once the requisite patches to project_issue have been committed will handle diffing taxonomy terms for both free tagging and fixed vocabularies. Obviously in the case of fixed vocabularies a user would not be able to add a new term to the vocabulary itself in a comment.
