Discussion forum for typing Q&A and review requests

[Sebastian Rittau]

Typing with Python is hard and constantly evolving. This is why we set 
up a forum to help users with typing at 
https://github.com/python/typing/discussions 
<https://github.com/python/typing/discussions>. It's fairly new, but at 
the moment we have two categories for general Q&A and for asking for 
reviews. If you have questions about typing, please join us there or on 
our Gitter channel (https://gitter.im/python/typing 
<https://gitter.im/python/typing>). If you maintain a typing-related 
package or typing-related documentation, we would be happy if you could 
add a link to the discussions forum to your documentation. Contributors 
to the forum and suggestions on how to improve it are most welcome.

The forum is intended as a help forum. Discussions about new features, 
improvements, and implementation should continue to go to the typing-sig 
list or to the appropriate issue trackers.
