Well there is one thing I'm especially interested about your past contests:
Where did you get your ideas?

maybe if we have 2 of us we may round up a posse!

What do you have in mind?

Students... we really don't have students on steem!!

That's wrong.
There is at least one student here on steem … and you are reading one of his comments right now.
Also I would guess there are a few more students hiding around here somewhere. We would just need to reach them somehow.
I thought rewards were a way, but you already tried that.
Maybe a high steem bounty would do, but that's too expensive and has a high risk of reaching nothing.
I'm at the moment using @contestkings to reach more people(That's where I used to search for useful contests.). Maybe that'll work out.
