Ultrapool is now open for signups. The current fee is set to 3%. Ultrapool has a distributed set of voting wallets in 3 different physical locations, with both IPV4 and IPV6 addresses, ensuring good connectivity to the entire DCR network. It's not currently listed in Paymetheus, but should be in the next release. I've been running my own set of PoS voting servers for my personal use since release, so I thought it might be a good idea to add a few more wallets and let other people use it too! Any questions, feel free to post here or find me in the Decred Slack.
