Dude to answer your question doing a "bump"on a thread puts if in the recent thread area and people can access it easy, but your only allowedbto do it once a day. And you can't do it to a thread that's older than 30 say's

let me tell you a tip... dont comment on a thread that has not been commented on for over 30 days, you get warning points, lots of warning points= ban

Being awesome is sweet
