You can actually use TortoiseSVN to checkout from github. I used it to download Tesseract and it worked fine. I tried TortoiseGit, and it worked as well, but I still preferred TortoiseSVN in the end. You can copy the https github link and place that link into the checkout URL tab in TortSVN and it will check it out and update just like a normal SVN. Food for thought also, I am very excited to get the github finalized, don't get my wrong. I just moved and I'm still setting everything back up. No worries would love to work with you on this though because I'm very new to the game. You know more about stuff than I do lol
