Are there any rules against bumping a post with no replies after a few days?

Like, to include edits and to bump it back up in the queue?

Sheriff: Yes. Don't do that. Also, the Forum Rules can be found at a tab at the top of the forum.
Forum Rules (http://www.giantitp.com/forums/announcement.php?a=1)

Double Posting
Posting twice in a row is generally frowned upon. If you are responding to multiple points, please use quotes and other post formatting to clarify this. Please use the Edit option to modify information in a post instead of immediately making a new one. If you do accidentally double post, you can delete the extra post under the Edit option.
