You forgot to mention who you are using as escrow.
Since you are brand new here and that many people have promised signature campaign participants payments but never paid them, there is a significant risk to anyone considering to participate that you are just going after free advertising.
All payments will be made every sunday. Since we are doing weekly payouts, we have elected not to use escrow.
If you choose to not use an escrow, people will choose to not join your campaign. Every campaign MUST have an escrow to prove it's legit.
