We really are fandom twins I stopped posting at one point too, and came back for a few posts every few years (trilogy announcement, Hall of Fame induction ceremony) and then came back regularly last August. I recognised Hermione as well and a few others. It's always been GDC for me though. I had no idea a Mike forum existed, that's amazing, lmao.
I don't really know. I left around 2010, came back and made a few posts when I saw that picture of the guys holding up the albums, and then left again. I don't think the trilogy really inspired me to talk about it that much. But the weird thing is I came back last year before the album or even Bang Bang was out, so maybe I just had a feeling it was going to be good, lol. I wouldn't say I stopped loving Green Day before that but I kinda stopped following all the non-album stuff, like Billie's acting and the side projects. Which I suppose was a result of not coming on to the forum
