I've gone ahead and created a slack community. You can invite yourself at http://slack.ffxiv-app.com/
It's another way to connect to other individuals. I'll keep an eye out and depending on user feedback I can change/remove/enhance it further.
Thanks for all the support!
I never actually knew this before (even having joined many more teams) that your email address when registering will be displayed in your Slack profile.
As this is meant primarily as a collaboration tool for discussions please only invite yourself if public display of your email for logged in users on Slack is okay.
If you accidentally register you can visit https://ffxivapp.slack.com/account/settings and scroll to the bottom to deactivate your account.
This is not something anyone's been using so I have disabled/deleted/destroyed the slack channel.
