Is it possible to send private messages to other users already? it would be a nice addition imho.
Not possible right now. Maybe in the future we'll have a full messaging system.
What is the best way to grant a download key to another user? If I can't send a private message, nor a mail, nor can grant a key directly to a user, then what is the recommended way?
You would have to ask them for their contact information. Sorry for the trouble
Pm would be nice! Sadly I got a lot of spam since I write my Email adress into my project discription.
