Make a sticky thread that lets groups list themselves?

Just as a try at having a go-to list instead of hunting through threads?

Can a moderator do this?

Yes, we can make sticky threads.
Any suggestion for a thread title?

That was fast!

Arduino User Group Registry Thread -- clubs register here, no comments please!

I did find a group near me but the search found it in an OLD Bar Sport topic.

Perhaps pruning the thread of dead link posts will be the hard part if it gets done.

I would second this notion. Simple title "Active user groups"
