You can have services anouncing and taking on bets synchronized with the site, and so much more. meanwhile after some trial period they can decde its not what they are looking for or comunibet has a reason not to aprove full membership.

This similar system  is what i used for over 10 years only a different branch.

So much scripts have been made already because of how long its been actively used, im sure you"ll find what you need thats beebn made already.
