first of all, its good that you guys changed the comment stuff, so you do not have to log in and register 100 times!
a request would be to remove anonymous postings as its simply stupid.
(not that it is possible, but ppl use it to post bull**** like:
yeah i am first.
or shout or flame other ppl.
another possibility would be hiring some Comment-MODS
which are allowed to edit or delete (hide?)
