I now have TTMod on the server, quick question as I am following the TTmod documentation, what are you using to open the .cs.dso files? I have tried Notepad++ and Notepad but they don't seem compatible, lots of squares etc.

you don't open them.
why would you want to open them?

No Idea how, yesterday I logged in and no notification that the trading posts was working (System Tray)
Today I have logged in at it's working!
