ERROR MESSAGE 1
svn: OPTIONS of 'http://crossroadscorp.unfuddle.com/svn/crossroadscorp_agi': could not connect to server (http://crossroadscorp.unfuddle.com)
I got this message because my wired internet access at a university has a firewall.
You can solve this problem by connecting through the wireless or by using SSL. Using SSL means switching from http to https.
ERROR MESSAGE 2
svn OPTIONS of 'https://crossroadscorp.unfuddle.com/svn/crossroadscorp_agi': authorization failed: Could not authenticate to server: rejected Basic challenge (https://crossroadscorp.unfuddle.com)
I've been using a free SVN service from Unfuddle. The problem is I thought they provided SSL but they don't.
Choose a service that provides free SSL such as Project Locker.
+ This demonstrates that I'm bad at reading. I was going to say that I'm bad at reading the fine print but that's not fair to Unfuddle who has made the information clear if one looks.
+ This took me ages to figure out. I gave up early on and purchased a wireless USB for my desktop. It is because I'm tutoring a subject where I've encouraged the students to use SVN that I've investigated further.
+ I don't really know what SSL is beyond that it stands for Secure Sockets Layer. Yep. There's also something called SSH and I also don't know what that is either.
+ Your SVN username at Project Locker is your email address! This took me ages to figure out as well.
+ I googled for quite a while but there wasn't any useful information, just the opposite actually.
