XMPP, while it is widely used other places in the deeper web, is virtually unused by PB2 (I'm the only person I know who used it prior to PB2)
I am proposing for the new site to have updated contact options.
This could include:
Discord
Steam
Gravatar
Skype
Email <-- maybe not this
But I feel as though it would be a great implementation to the new site to have more relevant contact methods.
