Maintaining is giving them too much credit, lol. It never worked properly and they would never support any updates or changes, so that's why it doesn't exist anymore.
So I am currently building a set of tools to replace it. I currently have separate plugins, but will try to integrate them all into one big one eventually. Currently have an account creation/login feature and HBD payment plugin that all work with Hive Keychain that work great. Next is a posting plugin. Been building stuff for Hivelist.
Reach out to me please, lets work together to charge the same battery
