How to plan and handle e-meetings
Based on your time-frame, you should have a scheduler (e.g. Doodle) or something similar in order to find a proper date. As a recommendation it should cover 1-2 weeks range and should be announced early enough and with a clear deadline, so you have enough time to announce the date of the meeting. If you cannot find a proper date, you can extend the doodle and add some dates, then remind your members to have another look at it.
