Thanks for improved discourse landing and some shoutouts

FTR, seems like @pradyunsg led the charge on recatorgizing posts to these sections, so thanks to him on that!

There’s still a month left to sign up and two to submit topics, but just a shout out to everyone to sign up if you’re going to PyCon and would be interested, and share any topic ideas you have! I see @willingc 's signed up, and if you’ll be at PyCon @lwasser we’d love to have you there again as well! Looking forward to seeing you all!
