Im in, aslong as you mean capture replays, rather than replay files for people to watch in their own replay theatre ingame. I'd love to get some of my shiznit online but lack of space hold me back.
GTRT is strictly for replays uploaded with a USB device. Those are : SharkPort, X-Port, MaxDrive, X-Ploder. I will personnally erase any entry that doesn't meet this condition and one already got erased. If that guy comes here, he will surely recognize himself. For now, I do not plan to support PC-video replay.
If you want to share them with everybody, I invite you to try either UploadHut.com or YouSentIt.com.
