  Some Students author Proposals to be reviewed by Reviewers (Mentors),
  followed by Hosts, who then convert them into Tasks (usually a single
  Task, in the case of GSoC).  In GSoC, this conversion of a Proposal into
  a Task grants the Student entry into the Program for that year, and is
  referred to as being "accepted".

  Other Students claim Proposals that were written by Reviewers (Mentors),
  converting them into Tasks (but only a single Task at a time can be
  claimed by a Student, in the case of GHOP).
