[X2Go-User] Japsand Maintenance Aftermath a.k.a. "Lessons Learned"

[Michael DePaulo]

Right now, I am able to connect to japsand fine.
1. That wiki URL loads successfully.
2. I connected to an LXDE X2Go session (only X2Go developers have access.)
3. I connected to an rdesktop session to the WinBuilder VM (although
someone else was already logged in, so I canceled.)
