Approve Comment — ??

When I posted a couple of times earlier today I saw for the first time an “Approve Comment” link in the upper right corner of my post after I clicked “submit.” The post also had a never-seen-before red background. Is this for the use of moderators, or is it something I am supposed to click on to show I really want to post it? I did not approve my own comment, but the posts appeared in the forum thread anyway.

I also noted a red tint/approve combo on a “SPAMMERS” post I made several months ago.

If I misunderstand the “Dev” category, please move this to whatever section it belongs in.
