Who To Send Amateur Radio License to For Group.io access

For some reason that group "AREDN" is tightly-managed.   I joined it, and then got kicked off of it for posting a link (!).    

But there are many many other AREDN-oriented regional groups on groups.io
For you in Yakima, the WVMN group in Willamette Valley might work for you.
Their web site is here: https://willamettevalleymesh.net

Alternatively, just search for AREDN on groups.io and see what works for you.

Hope that helps.
