user18586: I have just started to get back into chess from a long time away. I have joined my local club and started to compete. I have been playing around with SCID vs PC and wonder if you can link your opponent's online names under their real names, since I have been playing some people online and OTB. I am also considering investing in Chessbase, so if this is a feature available on there or any other chess database please let me know.

user24511: The feature you are describing is not built into either SCID or Chessbase natively. You can quickly rename players in a database, or alternatively automate through scripting.
I use the following API endpoints for chess.com to collect that information.
