Several things already discussed that brought up some nice ideas:
There are people here that dont like giveaways and for a time brought up the subject weekly with a new thread each week to ask for a seperate subforum for giveaways. The reasons were varied, but some kept mentioning "bringing the wrong kind of people here". This of course caused some discomfort, arguements and general nastiness on both sides of ths small rift that opened each time until we all got bored of it (seemingly) and then Grimwerk made a script that allowed people to ignore threads utilising the term giveaway, but a better idea was had prior to that - a new category for when making a post (much like we have with news and questions) for giveaways - but one that would only be visible to signed in members (this by itself would also calm some other issues / angles on it without segregating the forums and allowing this place to die out).
Obviously the rep system in its current form is FUBAR. Changes need to me made and I dont think theres an easy way around it to appease everyone. It has a purpose but that is abused and the community as a whole needs some form of input on it - but other than discussion, we need some positive action. How about it gets frozen for a week (other than spam reposts o fcourse or we'll be overrun by black magic love doctors!)?! - See if that lightens the mood a little to begin with.
The ability to lock our own threads might be useful in some circumstances.
A better PM feature that doesnt swallow messages so frequently and allows you some form of filtering.
Better forum search and filtering of course.
Licurg to be neutered (for the good of all humanity).
tinyE to perform previously mentioned operation (for our own amusement).
Less GOGbears,
There's probably more but now I'm starting to get silly!
Edit:
One more thing...
GOG should ensure when people want to know who won a GOG Birthday giveaway (and see the promised results), that it happens... O_o
