im trying to figure out how to add my chesscom userename to the uscf site, but i cant figure it out. Anyone know how?

Click on "manage my information" on USCF. Add site name and username under the "Online Chess Partners" section

thanks.

To follow up, when you check on the USCF site crosstables, are you able to see opponents chess.com user name anywhere?

No you only see real name
