Herculist.com is promoted as a site with an opt-in safe list. The idea behind the site is to give businesses a place to advertise with a built in database. Anything can be advertised as long as it is legal, with the exception of adult material. As a new member, you receive your own site. You use the site to login to the members area and submit an ad. You are allowed to promote your own site and you can earn commissions by sponsoring others. There are three membership options:

Free member may post an ad to 700 Herculist members chosen at random at no charge.

A Pro member may post every 48 hours to 49302 members and earn a 35% commission on referrals. There is a fee of $49.95 per year or $9.95 per month

A Gold member may post to 49302 members once a day and receive a 50% commission on referrals. This membership costs $89.95 per year or $14.95 each month

Herculist.com is apparently a dependable site, although you will be receiving a fairly steady stream of advertising coming to your email inbox from other Herculist members. You will also be able to set a vacation mode where you can send email but you will not receive any during that period.

Herculist.com comes highly recommended by many of its users and there do not appear to be very many complaints about the site. The commissions for referrals are an especially attractive feature about the plan.
