Welcome to Inkscape Community!
Oh, I like that graphic -- the gear coming out of the refrigerator! Now I'm imagining opening the refrigerator and seeing all kinds of jars and bowls with Inkscape logos on them..... Well, maybe I've been awake a little too long
This is good timing for you. There is some interest within the Inkscape community, to build an active Facebook group. You'll want to join the Inkscape user mailing list, at least, and post about your group there. I'm sure you will get some replies and interest.
https://inkscape.org/en/community/mailing-lists/ There was some discussion recently, although I can't remember the details (I don't participate in social networking myself, so I didn't pay close attention). I think they want to make an "official" Inkscape group. I don't know if you'd be interested in that, or if you only want to have your own group. But you can ask about it on the mailing list, if you're interested. If not, you will still reach a lot more Inkscape users by posting there.
You also might want to register on the Inkscape website, if you haven't already. Then you could upload some images to the gallery (still relatively new), and be able to keep up on the news, and stuff like that. We just added a Community To-Do List, with some important jobs that need to be done, but which no one so far has found the time or interest to do.
https://inkscape.org/en/contribute/to-do-list/ If you have any of those skills, maybe you would like to tackle one of those tasks? Some more opportunities are discussed here --
https://inkscape.org/en/contribute/ And of course, there is always the hard core developing and bug tracking type work too.
Thanks for posting! I'm glad to meet you, and hope you can build a successful FB group, and find a way to volunteer your time and energy. As Inkscape is finally approaching the long awaited version 1.0, it's an exciting time to be part of the open source process
