That would be really nice, up until now I was just subscribing to basically every community and even thought about just setting up one user on the server that subscribes to every community I ever come across but that would be kinda tedious. So if it starts to somehow work automagically for you I would just wait a few more days and see what happens.
Might be because the average Linux user is way more aware of how useful a crash report can be and therefore actually submitted them. At least most Linux users I know actually read error/ crash messages and not just call someone saying there was some pop-up, I just clicked ok and the game was gone.
