I did not approve a few accounts recently because (reasons listed below)
Your email address looked like a spam address
Your email address contained sexual terms - or gave the appearance that your intentions are not Christian.
Your name was to close to a moderators name - waaaay too close and may have created confusion
Your screen name is in use already and adding 1 or your birthyear doesn't change things.
Example: newsman 1 or newkris1970 (these are not the names, examples only)
Your screen name was inappropriate.
If your account is not approve within 72 hours, look at your proposed screen name and your email address, 90% of the time the problem lies therein.
