I'm not sure what you mean by "bump it."
Sorry. It's Freeper-speak for simply posting something (anything) to the thread for the purpose of "bumping" it to the top of the list of active threads in a particular forum.
One can simply type "bump" or "BTTT" (bump to the top) if you have nothing futher to say but want others to notice the thread.
bttt
You did the right thing.
