Hey there!
I'm new, so if I'm posting this in the wrong place or there is already a thread, feel free to help me delete it!
Just getting ready to send off my SSHRC from the U.S., and thought a forum to share updates,  questions, etc. would be useful.
I can start off with a question! Does anybody know if the P.O. box address that SSHRC gives means that I should not use a "request signature" option? That seems to make sense to me, but I don't really know. I definitely want tracking . . .
And does it seem risky to send it in a paper envelope that's not waterproof? Am I overthinking this?
Cheers!
