But I see the signature campaigns do not accept copper members.
Since this hasn't been answered yet: it depends on the campaign manager. I would accept Copper Members at Member rate, but I would also require them to have earned 35 Merit, to ensure their post quality is high.
I truly feel sorry for you if $12 can buy you food for a week
Why feel sorry? I wish I could buy a week's worth of food for $12!
a lot of the members here are very rude to poor 3rd worlders, I'm sure others here will berate you for not earning a single merit.
Only a few members are very rude. Most real users hate spam though, no matter where you come from.
