The questions needed to find the ansers are these: do you have two accounts? And if so, did you maybe forget to logout with one of them and posted thinking it was the other?
If the situation mentioned above is not the case... it could be your profile is fused together with another user's profile, which is a known glitch, but should not be occuring anymore as it was fixed, or so we thought. =)
Please email Ferret (ferret@armorgames.com), explain the situation and he can help you fix it, ok? =)
