I'm not so sure about summoning; all I know is that if you put the "@" sign before and after the username, like so---Winterfond, it turns into a link to that user's profile. Even if I were to be officially summoned, my ducks are also my guard ducks, and they protect me, and if anyone wishes to summon me, my ducks insist on a long, thorough vetting process, with stringent security measures. Then they nuzzle their beaks against me softly.
That's a quite an imaginative and tedious process. May your ducks always guard you and keep you safe. If ducks could actually do that... not saying they can't, not saying you're crazy. Not at all. Just being sceptical. The dashnhammit thing works. I got an email, in my junk mail, with a notification from you. So thanks for helping me figure that thing out!
