Proving Grounds reworked

[dfbovey]

Due to the popularity of PUMMEL, it's been moved to it's own sub-section. The Proving Grounds can now return to it's regularly scheduled programming. Including draw offs that feature more than two participants, the Grandchampionship series and other fun traditional draw offs.

All voting polls, discussion and weigh ins for PUMMEL should now take place in the PUMMEL section.
