Cluster did away with the annoying registration process, added proper FBT support and updated their pages with serviceable Engrish so I'm thinking of making a small Cluster exploration event this week, going around worlds, checking whatever event is active at the time and messing around with ingame world building tools.

Just register account at https://cluster.mu, verify your mail and upload any standard VRM avatar. You can easily convert your VRC base with UniVRM tools, instructions here https://clusterhelp.zendesk.com/hc/en-us/categories/4411636965529-Create-an-avatar.

Preliminary date is this Saturday around 11PM GMT.
