All moderators have extra links under gravatars in posts, like “edit,” “delete,” and “spam,” all rather self-explanatory. You can also see emails and IPs, please use that information wisely. Abuse will lead to you being removed as a mod, and probably from the forums entirely.
We have guidelines, not rules, for a reason: guidelines should be followed, rules must be followed. Never let the literalness of the guideline override your common sense. After all, we’re here to help people, not build a wall to keep people out.
There are always a few forums policies that we have to police more often than usual (bumping, code, etc). As with these and everything else mentioned before, this isn’t a job, so don’t feel obligated to police every single topic. Just keep your eyes out for anything that needs to be taken care of. We don’t generally care about the 10-lines-of-code unless it’s an entire css or php template.
Many of our members browse the “No Replies” section, so for the good of the OP (and to police no bumping), just delete all bumps within 24 hours of a post. If the member is a constant bumper, delete the bumps and comment explaining why we delete them and how they’re making it worse for themselves.
You’ll notice that topics have a pull-down resolved/not resolved/not a support question menu now. Some folks tend to browse the “Not Resolved” section, so settings things as “Resolved” or “Not a Support Question” is a big help when you can. Plugin developers can mark topics in their threads as resolved, too.
