Pretty much bang on I'd say....at least it mirrors my own thinking at this point.
- More devices = more queue id's = more chances.
- Bump that further by using a selection of different browsers eg Chrome, Firefox, IE on each device on the basis that each unique browser gives you a unique queue id.
- Take a copy of each queue id as you join so that you can reload it if things at your end, or their's, go belly up.
- Swot up on how to copy a queue-id and send to someone else to use. If you're in a trusted group then use your queue-id to buy for others (if your queue-id is spare obvs....), but if not then send it to someone else to help them. Remember that queue-id's cannot be used concurrently so remember to close your queue once you've sent it or else your buddy may get a 'queue id invalid' error.
