Ok, I'm very happy about this latest modification, because it took me a few days to figure out, as it involves some apache tweaking...
I have enabled Pretty URLs. If you don't know what this is, just look at the url of this (or any!) forum page. Instead of unreadable, esoteric, long urls now you get proper ones describing precisely where you are.
This is search-engine friendly, but also much easier for navigation. Do try various sections of the forum (boards, topics, member profiles etc) and see how it goes!
