Xbox Live has a matchmaking thread.
Didn’t see one here in the PSN.
It’d be nice to keep this updated with who’s still playing online, and for new members to make friends. 
I’ll start:
PSN ID: Engravings
Location: North Carolina
Main: Vega (Claw)
Others: Ryu
Controller: SFIV SE Fightstick
Skill: No scrub here, I put up a good fight.
