Perhaps a bit of an amateurish question but stay with me here.
I noticed in some of the earlier wayfinder 'zins that the side trek's are generally a good thousand+ words, but the submission limit for the side trek seeds are 325 words. I'm guessing the submission is more of a idea proposal or basic outline, and the full thin gets fleshed out later but I just want to make sure.
So, this Side Trek thing has sort of grown organically with the ongoing 'zine. We have Side Trek Seeds (early on just called Side Treks) that are the short 325 word summaries of possible adventures. Then we have Side Trek Adventures, 4-6 page mini-adventures that are fleshed out with a map, and NPCs....sort of a one-shot that can be dropped into an ongoing campaign.
So, we have Seeds vs. Adventures, short vs. long. Seeds are open for anyone to submit. Adventures are usually solicited, and are always approved by ME, the editor-in-chief. Seeds are not usually developed into Adventures, though....completely separate submissions there.
Very good to know - thanks for clearing that up.
