I do not know if anybody have posted this before because it have not yet been effected; there is no pay rates for the full member accounts and i am sure that this is just an error of omission.
Full members receive 450 GCSH from the signature campaign. Thanks for spotting this - we will update the thread as soon as possible.
Wait, Full Member is one rank lower from Sr. Member. In your post, Sr. Member can only have 400 GCSH. Maybe you still miscalculated the payments. Sr. Member should get higher than Full Member.
