OrgyMania (SlipShine) review
The OrgyMania address opens Slipshine’s own landing page. Slipshine describes itself there as a webcomics publisher and separates public entry from access to the members site.
A publisher’s catalog behind its own entry page
The landing page says the characters in its comics are adults. It distinguishes a free area from the members site and notes that access may vary by location. The available issues and reader controls are beyond the public entry page.
What you can browse before joining
Slipshine’s entry page describes the publisher and sends members to card-based access, with billing handled through CCBill. Welcomix makes its series index and descriptions public. That gives you more to work with before subscribing if you have a title or a type of story in mind.
Anabel’s take
I'd look for a particular artist or series before joining Slipshine. I'd choose membership for a catalog I wanted to explore, and I'd wait to see what issues were available before deciding how long to stay.
