A short overview of the current 10k tools pages.
This page is mainly an overview of questions that might be worth closer inspections. I guess it is pretty self-explanatory. I usually have a look at the recently migrated questions (because they often need attention), the new tags (because they are often an indication of mis-tagging) and negatively voted questions. You can click on the triangles to expand the lists (this of course also applies to the other pages).
migrated: A list of all migrated questions. For the current amount of migrated questions per day the list on the stats page is long enough. So this page is pretty useless most of the time.
close: Lists recent close/open votes and recently closed/reopened questions. I usually go through this list once a day and add my vote to any questions that I think should be closed (or sometimes a comment that I disagree with the votes). This makes it more likely that a question that should be closed gets five votes.
delete: Same as the close list, but for deleting questions (once a question has been closed for two days, you can vote to delete them). The page also lists answers deleted by mods, but does not list questions an answers deleted by their owners. I usually find this page pretty useless (though it is probably more valuable on bigger sites).
flags: Lists posts that have been flagged by users or by the system. You can go through the list and add your own flags. On this page (and only here) you can also flag a flag as invalid. Adding additional flags can help the moderators to prioritize they actions (though this is way more important on bigger sites than on TeX.sx). Also SPAM posts are deleted automatically when they accumulate enough flags. The page doesn't list flags by moderators and non-specific flags (the 'other' flag) and once you took some action on a flag, the system won't show you that flag anymore.
For posts automatically flagged by the system it might be possible to improve the post or at least add a comment to inform the user of best practices on SE sites.
links: This once had a lot more pages linked than it has now. There is a link to a list of past suggested edits, which can be interesting if you want to look something up (e.g. if you suspect some strange edit pattern), but isn't that useful otherwise. There is also an (experimental?) page that show some stats about feedback by anonymous users and users that aren't yet allowed to vote. Doesn't seem to be particularly useful at the moment.
In addition to the above pages, the 10k tools menu bar also links to
/review, but I think that page is accessible to all users. 10k users also get notified on the top bar of any pending suggested edits.
