Hi Sylvia,
Welcome to 5 Star. Sure you can post your offer here in your intro or in the merchant "announce your program" section as well as in your sig.
I want to faciliate contacts and trading of info and as long as people don't get too self promotional and carried away. SO YOU'RE SAFE!
PLUS just took a peek at your site. Refreshing change of scenery from most ad and affiliate networks. Just realized they all look the same and have the same tone. Yours is different and stands out. I like it!
