[Asterisk-Users] Peer Review - Linuxfest Presentation Outline

[Greg Boehnlein]

Hello all,
	I've been invited to do a presentation on Asterisk for the Ohio 
Linuxfest in Columbus this weekend (http://www.ohiolinux.org). Rough 
estimates are that nearly 500 people will be attending. I've been working 
on an outline for a couple of weeks and I would like to have some peer 
review of the information presented.
	I am going to have to cut down the content to make it fit in a 40 
minute presentation, leaving 10 minutes for questions at the end. Please 
feel free to tell me I'm missing something, fill in the blanks, yell at me 
or whatever. Some questions to think over while reading;

	- What is most important for new Asterisk users to learn?
	- How can I help get them started off on the right foot?
	- What are the high priority items?

	My goals in doing this presentation are to make sure that the 
Asterisk community, Digium and VoIP are presented in a non-biased, 
informative and community oriented manner. Hopefully, we'll get a lot of 
new Asterisk users, and win over some developers to help with the project!
