yeah, I only saw very few and those that were, not very active.
mastodon is great. but while it is missing a group and event function, it might be not suitable for people that expect such functions to be there.

When joining mastodon with such expectations ppl might become disapointed.

But there're other plattforms that are also part of the fediverse that do so.
#Friendica and #hubzilla for example.
(instance for hubzilla: hub.libranet.de or hub.disroot.org)
