Well at the very least, the forums should have one thing your USBs do not, that could only help you. But yeah, there are many storage methods you could choose from, and you could even do all of them to be as secure as possible. A website like google drives that stores your items, but doesn't necessarily share the files unless told to do so. External HD and usbs. The forums as well. You could also post the rp here I am sure. I'm sure there have been some big projects on this forum in the past. I can't remember if you brought it up that you were or were not going to do the rp on here.
