Those who complete (compleat!) the Munros can record this fact and receive the magic number by writing in to The Clerk of The List (See here). Additionally, a list of current compleaters is published annually in the SMC Journal.

Richard writes: A total of 25 of us reached the top on a superb spring day, the early morning cloud burnt off leaving great views and beautiful sunshine. There were 7 first time Munroists in the group that day, six of whom were under 10 and made it all the way up and down under their own steam. We had time to chill the champagne in the last remains of the snow just below the summit.
