I know that if you played in a game then that system will be added to your subweave. Is there another way to add a system to it? I have a growing interest in Call of Cthulhu and I would like it in my subweave, but I do not belong to any games for that system.

Not at the moment - there was a whole interests & subweaves system I set up but there were problems that led to it never getting completed.

At one time creating a sheet would have achieved your goal. Don't know if Rigo has changed that, try it.

Nope. Didn't work. Thanks anyways.
