Fab Swingers review
Fab Swingers has member profiles and messaging. Its FAQ distinguishes ordinary mail from a supporter feature for keeping messages you want to find again.
Save the conversation if you need it later
The FAQ says supporters can move mail into a saved folder. It also describes the site’s separate chat room help. Fetish.com gives you another profile-based community to compare if member discussions matter more than one conversation.
Keep profile and messaging choices separate
Browse the profile controls and the messaging help before setting up an account. The public pages give you a picture of how people interact. Check the supporter description on the site for the tools attached to it.
Anabel’s take
I’d look at profiles and the conversation tools first. If I wanted to keep a few messages for later, the saved folder would be a concrete reason to consider supporting the site.
