4. How Do I network With Open Canvas?

   Generally if you're getting a connection error with OC it is due to a router problem, you can use Hamachi to create a virtual network that allows one to connect.
   
   There is also the option of using Warpaint I may end up creating a server for this program as well.
   

I'll add any other questions later or go in depth in case users have more questions.
