New `pollen-users` repo for Pollen discussions

[Matthew Butterick]

I’ve set up a new repo to use as the successor for this Google Group:

https://github.com/mbutterick/pollen-users

We'll post the threads in the Issues section and see how that goes.

If you have a GitHub account, then you know how it works.

If you don't, then you can set up a free account with your email address. 

If you want to get an email notification every time a new topic is posted (similar to how this email list works) then use the "Watch" button at the top of the page to set your status to "Watching".

As I mentioned yesterday, this group may already be targeted for destruction by Google. So citizens of `pollenpub`, I hereby invite you to migrate.
