What would you add or remove from the site if you could?
Oh dear...I can go on and on with many different things as I come across them.
There's a need for a lot of damage control of the moderation system between users. For social users, there isn't much of a problem, but a lot of the UNL Members develop that "I pay so I should be able to do whatever the hell I want on the forums" attitude and they get slammed when I have to throw the book at them since it's a breach of the site's TOS.
Probably the main problem is that the site isn't what it used to be years ago when most of the regular users of today were not here. The site grew A LOT but the staff hasn't done so that much. The amount of new demand on a staff that has only a few new members to develop and push trainers out is taking it's toll on the administration (I recall seeing that Caliber was working around midnight to update a trainer to keep the site up to date with the games).
Overall I think an expansion of a non-moderation staff that can help Caliber and PWizard and Nevermore each do their specific tasks would help out a lot. The only problem standing in that way is cost.
Another thing I would probably add is more variety in punishments. Yeah some members are extremely ****y, but the only solution is to swing the ban hammer if they don't stop. Two methods I'd probably add are temp bans and account mutes. The former simply banning the person for a limited time instead of permanently. The latter being the ability to simply take away a user's ability to use the forums (but still use trainers and etc). Posts just are not that big incentive to keep the members who only care about trainers and posting on the game boards.
I think that's all I got for now.
