@daeus-lamb Thanks for answering.
The main reason I don’t want to use my real address is because of my parents, who tend to be slightly paranoid about things like that. It would take a lot of convincing for them to let me use their address, and since I move around so much theirs is my only stable address, if that makes sense.
I don’t know if it would be worth buying a mail redirect address. I don’t want to make any financial investment just because I’ve put in so much work already with very little result, so I can’t help thinking it won’t be worth it.
