Hi Nathaporn,
Spoke to our IT about what we can do to potentially improve the performance during the training sessions, and it was suggested that instead of using GoToMeeting if there was a computer that I could connect to run the application locally through VNC software, it could be an option. But with VNC I understand that only a single connection can be made so not sure how we’d be able share screens for multiple offices. Perhaps you have other suggestions.
Then we could use something like Skype for the sound portion
Tks,
Mark
