I just found very hard to make links more friendly with apache's mod rewrite.
When i tried to make the rewrite rules it always gave a wrong path because there was always a sub rule replacing where it shouldnt :\
I gave up from it because i realized it would give me more problems then the ones that i already had with my dinamic links (few traffic, not really functional problems) because despite they are so unfriendly they always work how they are suposed to lol :)
