Right now. The default start time for Scheduled Meeting is 5 minutes. It is better to setup by the user.
Thank you for your feedback. This is a good suggestion - to provide a configurable "how much time before the meeting do you want to start the meeting".
Please let me know if you have any more suggestions. You can mail me at uday(at)dimdim.com
Has any work been done on this? This time frame give the presenter such a short window to start the meeting. If they get tied up with something they have to start a whole new meeting.
