I am interested in your "COMMUNITIES" plugin, but it says

Hello,

I am interested in your "COMMUNITIES" plugin, but it says I need a multi-site... does this mean, I can't use this plugin if I want to use it for only my ONE site? I don't have more sites at this time...

I essentially was keen on the COMMUNITIES plugin because I would like to start a chat community network among my site members, so they can network together on projects and exchange ideas, etc... to create a real "community" feel among members.

Thank you for any tips, direction you can offer on my ONE site, and if still possible to use the COMMUNITIES plugin...

Cheers,
Tany
