I have recently reached the possibility of using the "review queues". Often and willingly I try to help the community of Stack Overflow as I can, focusing mainly on the "first questions" section.
The problem that I very often find is represented by this discouraging message:
The edit queue is full at the moment - try again in a few minutes!.
Discouraging because after having corrected an answer syntactically, conceptually, etc. etc. and having, therefore, taken the time to make sure that this was as correct as possible, the above message appears.
As written in this post, it is clear that the the suggested edit queue has a fixed size and as written in this post it is also clear that saying that the post doesn't need any improvements when it really does is wrong.
At this point, it becomes really difficult to be able to make a useful and effective contribution if the message "The edit queue is full at the moment - try again in a few minutes!" appears only after pressing the "Save edits" button.
So in conclusion, what I would like to do with this post is discuss about some possible solutions that I have found:
Once the "first answer" section is open, highlight, in the box of possible actions, the fact that the "the edit queue is full at the moment" so that a person doesn't even start correcting the answer.
Before entering a question in the "first answers" section, check that the review queue is not full (or in any case there is at least one place always free, for the person who will access it through this section).
Your ideas / opinions.
P.S. Consider that the specific use case I'm bringing you is Stack Overflow, where a question has a full edit queue after a few seconds.
Furthermore, also consider that access to these queues occurs only after having achieved a certain reputation, therefore it always offers the possibility of submitting an edit to those who want to help others more scrupulously than those who are always ready to edit every single answer competing with other users to get a meager +2 reputation, seems to me the least (for the avoidance of doubt, by "more scrupulous" I mean that the system still has its own metrics to understand if the work done by a user is correct. And if it isn't, it restricts their access to these particular queues).
