If you don’t want to upload it to Youtube, put it up on Vimeo or ImageShack (I think you can upload video there. If that doesn’t work, I guess just youtube. Once uploaded, post the video link on the forums.
Yeah, Youtube is a pretty easy option. Once it’s all uploaded and done, just take the address of the video and put it in the text. You don’t have to embed it here with any embed code. Just the link. Hope this helped, and I can’t wait to see the video!
