Hi, first off sorry if this isn't the right location for this thread.
What I am wondering is if there is an easier way to share a file with a friend we are both going to be making a map together and I feel like there must be a better way other then me saving it maybe three times at a certain point and sending it to him or vice-versa. Is there a way we can have the file linked between both computer so every time he saves it will update the file on my computer too. Or just in general an easier way then saving it and having to repeatedly send it to the other person. Sorry if that was confusing.
Will cover everything you want to do. If you need some help with setting these two up send me a PM, I manage my corporate team's Dropbox Folder with an SVN in an enterprise situation for doing exactly what you're wanting everyday.
