1-Email a user & all users also a newsletters system
2- processing fee feature to cover payment gatway fees
3-Create service bump feature to bump a gig to first page and set fees for it example 5 bups for 5$ or 10 bumps for 10$ ect... And ability to set it to give free bump each day for user login ect...
