The idea is to get your name against the "last poster" for every single post on the front page. The problem is that as soon as people realise what you're up to, they start knocking your name off the posts, so you have to keep reposting to the knocked off ones as well as doing the new ones, then it becomes competition of speed and juggling. Bit like the old game Missile Command.
