This just happened to me, and I was wondering if it's happened to anyone else or whether it was just a weird glitch caused by my computer's cookies or something. I posted a thread in one forum only to have it show up in another. And yes, I know for certain it moved on its own, as I clicked to return to the forum it was in and got an entirely different forum than the one I was surfing. Hopefully it doesn't happen too often, as that could be a headache for moderating the site.
Anyone else have this happen?
