My character is level 24 and I've unlocked the guildhests through level 20, but the daily roulette only gives me level 10 guildhests. Why is the daily roulette only letting me do level 10's?

Also, why can't I post in the regular forums? I get this message when I try: New thread cannot be created due to either you have reached to your daily limit or your main character's level is not high enough
