I hope this is the right place to put it...
Maybe a new sub-forum?
It should be called the RPG test drive section.
Basically, the idea is that before the RPG starts but after the Sign-Ups are done, the GM can make a "Test Drive" topic.
A test drive topic would basically be the beginning of the RPG, to see if the RPGers would contribute enough to it, so the RPG wouldn't die.
I think that it would stop the amount of dying RPG's in these forums.
Also, it could have something like a 4 page limit, so it doesn't go on for too long.
When the RPG would start, it'd start from the beggining, but there would be a slim chance of it dying.
Is it a good idea?
