Bump Thread?

Is there a way to bump your thread? If I'm editing a thread about my map I posted a while ago and have updated news and pictures i would like to have critiqued, How can I get feedback if it's buried 3-4 pages into the subcategory? If bumping isn't already a feature, I would suggest looking into it, or a type of bumping. Such could be like a notification that certain threads have been updated on page 2 or 4, etc.

What do you think?

I see, That makes sense.
