One more point.. It would be easy to make posts in a highly active forum. For a forum with low activity, it is almost impossible to make such a large number of post per day. Also one more question.. Is this totally a hypothetical question or you have some vacancy for forum posters?
i love forum posting but 500/day....NO Way i am going to do that until i am being paid 500$ per day you know you have to sacrifice your entire routine to cope with that number BTW u didnt mention what was ur pay scale?
