i think unregistered users should be allowed to make submisions to the site, it's the same as with registered users who don't take the effort to make any correction in 3 days----->result is the same. correction by a mod or rejection.
As i already mentioned earlier this week: it would be better to be able to correct basic stuff at tabs in the qeue instead of just suggesting. cause a lot of tabs are approved by spam-approvals by people who want easy iq. so correct them before that happens would be a big advantage for the site. but i guess it's all or nothing here.
