For what it's worth, I've just been through the 'throws' of organising OZFEST 2004 (see: http://www.flyertalk.com/forum/showt...34#post2846434). For this I needed to stay in touch with probably 30-40 FT'ers.

I started using the FT system and it didn't work for me:
- only 70 messages total allowed
- only 5 can be contacted at the same time

After the first go I started asking people to email me a private address so I could set up a 'Group contact list' within my own system. Towards the end of the exercise I was able to reach 90% of the people with one hit!

During the process I also had to delete many messages, just to make sure that my FT 'inbox' stayed relatively empty...
