Ill give you the high and low.
Two members here (one ex actually) called andy and burke have a liking to playing their tricks on the forum by creating fake accounts and posting garbage. Emma is only suspicious of you because Burke, (the ex member) had a disliking to her and you have been frontal (something she is not used to as everyone loves her). So yeah, Emma and all the others are just wary of you being a creation of Andy's or of Burkes.
Perhaps its because most members have an inferiority complex before they reach 2000 posts though, something which you havent suffered the symptoms yet.
Damn postists.
