There area few reasons why people can't send you mail: 1) They haven't earned their FunMailing privileges yet; 2) They don't have you as a follower; 3) They are not including a subject title when sending you mail.
used to be able to but i think the admins made it that way cus of spammers/advertizers.
stick around, answer and ask questions to get your points up and itll all fall into place.
maybe its blocked somehow? or maybe its not properly working the correct way.
You dont have enough points, I believe thats how it works.
new members havent earned there privileges to funmail yet.
How do you know they aren't?
