I've been on UMD for years, but only recent found the games forum, so I suspect I'm not the only one to have missed it.
For those who complain about the lack of female members on UMD, we currently have 3 girls as "slaves" in the Wam Dungeon: https://umd.net/groups/the-wam-dungeon
I recently received a messy punishment from that game & have attached a photo of the end result.
