@Greatdaysfan, please don’t, as @tclaus suggested, ‘vote’ or say ‘I want this’ on any open GitHub issue. That doesn’t help to get anything started, and just creates ‘noise’ on what is supposed to be a tracker for software issues and development.
If your question is how to start groups within Diaspora itself, then this is unfortunately not yet possible. These two long discussions give an idea of the current state: Feature Discussion: Groups and Add support for groups in diaspora - #36 by imbehind
If your question is how to start new groups or sections right here in Discourse, then that is only possible for admins to do.
I hope that helps.
