For the cost of a MUAC membership ($40/yr), you can climb at the wall. Come along on climbing nights for a wall induction and get your own membership card so you can access the wall outside of these times - but remember, never climb alone!
The Wall Officer for 2020 is Will Barker. Payment can be done to them on Tuesdays or Thursdays or can be deposited to the general account. See here for more info for payments.
