Thanks for your reply. Yes, you do understand me correctly :)
OK, I will start building a running community here at Steemit.
I will start with a proper introduction and guidelines. Something like this post on a lesser scale.
I will 'keep it together' with #steemitrunningclub tag and with moderating. Of course, I will need / build a team of moderators. There will be events, weekly digests, ...
The promotion will go through Steemit and related channels. I will also use other networks to attract members.
May I notify you when The into will be ready to be published? You just might help to launch it. If you feel like it, of course.
It may be a model of how to build a community here :)
Thanks for your attention and help!
