I and most likely others will find it annoying to be in the market for example and see this thread http://sythe.org/showthread.php?t=1295955
with the title
"HistoryLes Gold shop! Cheap Fast & Reliable .50/m[PP][WU][Mail]" and we click on it only to find that the prices have since gone up and are no longer 0.50/m. I know that you can request a thread title change but really it just gives moderates more work to do when they could be doing more productive moderating. I suggest that members are given the power to be able to change their thread title, now your main argument would be abuse? So imply a hard rule on abusing this function and hefty amount of infractions or a temporary ban.
