Originally, when forum was re-opened, I saw this issue, but decided to wait a little bit and see development of forum. Today, when we already have good number of various posts here, it is a quite obvious, that extending the number of groups in forum will be very beneficciary, have better structure and make search easy for users.
Today most not games/problems/openings related posts go under two groups only - General Discussion and not checkers related group.
However, if we look at postings, we can see, that they can be better organise.
I propose instead "General Discussion" create such groups as:
1) Checkers Promotional discussion
2) Federations.
3) Collectable and memorable.
etc
For non-checkers related things we also may have new groups like:
1) Greetings
2) Politics, weather, sport

3) Announcements (tournaments, funeral etc)
etc
Today, when total number of all postings, since forum started, is relatively small - only couple hundred, and if you decide to create new group - you can manually move posts into right location. If you decide to delay this process today - it will be much harder to do this later, because number of posts is growing every day

Think about ...
