About languages, why not just one group, and ask posters to prefix the title of their post with [COBOL], [C], [PL/I], etc if it's about a specific language?

this could be done with the use of # tags, however it is (always) down to UX, will members adhere and/or understand. Could be better to build out groups for languages etc based on content/activity. In the near future I'm hoping to focus on individual groups and grow members, content, activity and momentum
