I'm testing with PHPInSim, and I don't know so much about InSim. I have tried to put your example for sending a welcome message in PHPInSim, but don't sends the welcome message.
I put the function call to the message like this, its correctly?
I am triying to learn to program InSim with C# (I am a noob with C# too). I know the existence of the InSimLib, and other similar libraries. Also have a project in mind to perform in C # with InSim.
