FLIK ROLL, there's nothing in the rules against solo spinning provided you follow the usual safety rules.
Some words of caution:
No two spins are exactly the same.
Some aircraft are very sensitive to stick position and have interesting spin modes; ... make sure an instructor has shown you any surprises that your particular type may have in store for you before you spin solo.
Wear a parachute, pre-plan your abandonment height and remember to check the altimeter as part of the recovery.
Spinning is great fun but needs to be treated with a little more caution than some other aspects of aviation; why not do an aeros course?
