The queue is open again with a per user max limit of 10 unapproved submissions, and a global limit of 50 total unapproved submissions. We will tweak accordingly if necessary. We've also recruited all suitable volunteers from this thread to increase man power.
This should get us by for awhile as we continue to work toward eliminating staff. Plenty of good points and thoughts were brought up in this thread. As with many things there is no easy answer. I think all ideas presented here had some valid criticism. I usually go for for a balanced approach in such cases.
I will probably offer a file rollback limited to a time frame that works reasonably with our resources. Then, the groups able to approve/reject and rollback (perhaps a different group has rollback privileges) need to be limited by some mechanism. I'm uncertain yet what that mechanism should be. We have seen ideas like post count, nomination, and submission count. How about length of time being registered? We definitely want a mechanism that would not facilitate factions or other abusive group situations. That probably means karma, polling, and similar are out.
stahl:User education is definitely a huge part of it. Poor submissions from uneducated users require heavy time consuming scrutiny, while some of our top quality guys could be approved near blindly in seconds. We could really use someone to write up more educational passages, continue to rewrite and clarify policy, or work with submitters to improve their quality, and items like that. There's often good ideas, but nobody wants to do them. Any interest?
People these days use the magic tools in our database and don't understand how to identify a ROM, what a header is, or any of that. Others can't successfully use Zebucket Dropbox of fileden for a direct links. Some people don't know you can edit entries on the site and try to submit edits as new. Some don't bother reading the guidelines at all!!

Then, there's the language barrier. Some users simply don't understand anything we say let alone the guidelines! No hope there. We sadly have to ban such users at times because we can't communicate effectively.
