250 posts is easy!! get involved in a couple of GD threads, have a row with fox in motors, he likes a good argument you might even get some financial tips from the motors community. Then have a what would ultimately turn out to be a pointless debate with stockhausen in SC ( loads of posts to be gained here as he doesn't listen to logic) and then have a squirrel image fight with ^TANK^. Then if you get really desperate post hello to all the new members. 250 posts easy peasy.
I like it just the way it is anyway, 500 posts may not be a bad thing anyway as active posters can easily rack up that amount and with that amount of posts people get to know you. Bit more reassuring buying from people you kind of know.
