As 'dwheele' ran
svnadmin create /home/dwheele/my-repos
This created the repository, but I couldn't connect to it from my workstation.
Needed to open up port 3690 on the StopsToGo droplet. So I used this
sudo ufw allow 3690 sudo ufw disable sudo ufw enable sudo ufw status
This uses the UFW (Uncomplicated Firewall) functionality which internally modifies iptables.
Had problem when using the client because I needed to use svn://stopstogo.com/home/dwheele/my-repos
