So many Ninjas...
OT: I guess it has it's good and bad points, and most of them have probably been stated already :) I like the idea, but I can understand the problems that people hve with them; if it was there, you should be able to turn them off for yourself.
A forum I used to go on had some fairly interesting stuff on it, like changing the colour your write in and baing able to post pictures directly into the forum, obviously this did mean that trolling people with nasty images would be easier, although moderation should be the solution to this.
Having said that, Bungie aren't maintaining these forums and I don't know who, if anyone at all, would be able to implement these chanegs...
