title_body: What are Catalyst "challenge setting" challenges for? I have a solution idea that can be solved by Cardano and couldn't find the right category for it.  I want to put it in the &quot;challenge setting&quot; challenge.
  Do &quot;challenge setting&quot; challenges have limits on what can be proposed?
upvoted_answer: A &quot;challenge setting&quot; challenge is how the Catalyst community chooses the themes and funding for some of the Catalyst challenges following the next six-week cycle.
  They are significantly different than most other challenges.
  
  No reward is given to proposers
  Proposals suggest new challenges
  They do not contains proposals or solutions
  Funds requested become the budget of the challenge
  The outcome takes 3+ months to complete
  
  There is a long lead time on funds proposed in the challenge budget being delivered to the proposals that win in the resulting challenge.  If the challenge has a timeliness component (e.g. a &quot;Women&quot; theme to coincide with = International Women's day) it is best to propose it about 90 days in advance.
