You got it!
There are a lot of steps involved, but a good rule of thumb is - figure out who publishes the sort of story you write, and submit it there. So I might eventually try to get a story published with Del Rey or Baen, while your story might be more likely with Scholastic.
Isn't Scholastic all PCized anymore, though? I dunno if they'd accept anything with intact families and kids hanging out unsupervised with older ladies...and enjoying it. Heh...but maybe I'm just bein' cynical.
Hm...I'm betting my brother that works for Ignatius Press could tell me what companies to check into...if he'll give me the time of day with regards to my writing.
*sigh*
