Going to ping those who I haven't seen visible two-way communication. I'll be doing a last check and subbing out inactive people after the next 24 hours, so if you're communicating via Discord or some other medium that is not the Smogon wall, post here (or DM me on Discord) to let me know.
1 sided communication:

I've also updated the OP with all the wins so far. Do let me know if any are missing. Also let me know if there's any communication I've overlooked.
