I am trying to get submissions for a high school student-run arts/writing magazine.
Where to you recommend us to get submissions from?
Are there any people interested in being editors?
Your HS? Other nearby HS?
You can start at your school - if you have a creative writing/art club, you might want to start there, or work with your English teacher to get some students to submit (maybe even for extra credit). You don’t have to limit it to just your school, though, there are so many talented artists and writers on the internet, and I’m sure lots of them would be proud to see their work published in a magazine! You can try forums like CC, or other social media sites like Instagram, Twitter, or Tumblr (I’m pretty sure there are a lot of artists on there).
Good luck! I’m not 100% sure if I could actually commit to being an editor, but if you have any more information I’d like to hear it.
If this is in school, get some people who would be interested in helping to lead the club. Then, I would ask at lunch. Just walk up to people and tell them about it. It’s always good to start with people you know. I hope this helped. 
Trying to make a high school magazine for all high school students, not limited to our school.
Thanks guys helped a lot!
