There is always the search function (for fuschia, for example).
Every addition or subtraction continues to add up. IMO, yes, it would make a difference.
Early on, if I recall correctly, Dave tended to feel the same way as me, but was and is happy to acquiesce to new forum requests (with a sunset clause), of which there have been many. if we keep adding, without the ability to subtract, we'll end up like gardenweb with 500+ forums. Yikes!
