Contact retronical
Your message will be emailed to retronical but we wont send them your email address. Instead we'll send a link back to your profile page here on looperman. Don't over use the contact forms as this may result in your account being suspended. Nobody likes to be spammed.
Don't contact users to say how you used their loops or acapellas etc. Post a comment on the loops or acapellas page instead then everyone gets to hear your stuff.
