Although I think the APUG magazine is a fantastic idea I think of all the work it would saddle Aggie with. I've spent most of my life working for newspapers or print shops and I know what a colossal investment in time and money any publication is. The magazine needs to be started by someone who is absolutely passionate about it or they will become disheartened rather quickly and find other avenues of expression. If Aggie wants to be that person I applaud her, but I'll not try to push anyone into it for humane reasons.
Aggie if you were to do this I'd recommend picking Steves brain clean for any thing that would help make the job easier or better. He probably has a good bit of networking in the industry you could make use of.
Of course if this project means you won't have time to make pictures then stay away from it!
