If you are at SDCC right now, run! No, there's no need for a panic face, but run! Joe Harris and Joe Corroney are signing autographs for fans at 12PM local time at the IDW booth #2643, convention floor. They both have their own booths in the artist's alley. Joe Harris is at BB-03 and Joe Corroney is at GG-08.
And if you can, stick around until 5PM for the IDW: Comics Make For Great Games panel. They're gonna talk about the much anticipated X-Files board game out this summer! You may even get to play a game or two. The panel is in Room 4.
