When it comes to join pages,
Sexmoney.com has the best. Why?
1. Enable/disable join page exits/popups (all with your ID)
2. Clean Layouts:
Layout 1 /
Layout 2 (this one can be costumized)
3. Geo targeting (mostly in the language of the surfer)
4. Recurring or PPS
5. Enable/disable upsells (all with your ID)
6. Lots of livecam and other upsells in the members area, all with your ID!
7. Tons of Niches that you can use the Joinpage for, all of them have great member areas!
I made most of my money with those joinpage links on my own design.
