It's current title "General RPG Rules Discussion", is IMO much more confusing than the original "Pathfinder/OGL/D20 GAMES". Since we now have a specific 4e rules forum and 3e rules forum, the concept of a third forum for general rules seems excessive, redundant, and confusing. Also, the description Morrus gives of it makes it feel very much like a general discussion forum, and not crunchy like a rules forum should be. Finally, very few posts in the forum are about rules themselves. Most are about general non-D&D RPG discussion or house rules. This can only lead me to the conclusion the word "rules" needs to be removed from the forum title. Something along the lines of "General Non-D&D Gaming Discussion" seems much more appropriate.
