Anyone can apply for a spot by changing their signature and making an enrolment post. I will then PM/reply to each request made as soon as possible.
This way of manual approving members is only temporary until a solution is found using the bot.
Why make it temporary? If you did it this way you could automatically deny people with poor post history, thus cleaning up your campaign in the process. It's because people don't check users first that they post crap and when this goes unchecked and they realise they're getting paid to post crap the quality gets worse and worse.
The need to make an enrollment post before approval or denial is temporary (sorry if that wasn't clear enough). The bot is being coded to avoid the need to post an enrollment post (you'll just need to register and I will sort through applicants, either approving or denying them). The bot will then PM the decision to the applicant. Hope that makes more sense now (basically, the solution would still require my manual approval).
