Is there currently a way to "bump" a post?

It was a thread on something about being able to change a user’s rank using a Roblox api instead of having to use some external server. So could I reply with something along the lines of,

“Adding something like this to the Roblox engine would be greatly beneficial to me as I have been trying to figure out a way to automatically rank people within my group but have found no success as it is a somewhat complicated task to do and I currently do not know much about this.”
