Advice to Improve a HS Literary/Arts Magazine?

<p>Yeah...I guess it's a pretty vague question, but does anyone have any advice as to how to improve a high school literary and arts magazine?</p>

<p>My high school has one, but it's not very well-known, and it isn't that great either, but I'm hoping to become the editor-in-chief next year, so any tips? Suggestions can be about anything, from organization of groups, criteria for submissions, how to advertise it, time management, etc. Oh, and a list of competitions would be nice, too.</p>

<p>Thanks! :)</p>
