Am sitting on a Dark Souls gift because I can't figure out this fucking Modbot system. The OP is confusing me. Do i need to send a PM to modbot with my "receive your gift" link first, and then keys are sent to me so I can write the "register" PM to modbot? Or does the "receive your gift" link get entered in the "register" PM in place of the keys? God damn I feel stupid right now. This is what I get for doing this for the first time while at work.
Theres a separate procedure if you want to send modbot something that's listed as a gift in your inventory.
Basically.. send the gift to yourself via email from within steam.
You'll get an email with a url link. You don't need anything after the ? part of the link.
Send a PM to modbot with a topic saying "register" and list the game and the url
It'll send you a reply back that you cut and paste into the thread.
Hope this helps, if you need help, let me know.
