Reenrollment is easier just after payment, because payment is notified. Now i have to wait for a slot to reopen and to race agains a guy who will be notified by its payment. So it will be harder for me.
This is not very fair to me.
Everybody else is bound by the same rules, and there are several interested parties waiting for Senior-level slots to become available. This is the fairest method I could create without affording preference to existing enrollments. I chose to use this method to maximize availability for all Bitcoin Talk users.
Not that this means anything right now, but I don't intend to immediately re-enroll into my slot since there is a lot of demand.
