I have a list of 20 names in Column A of my spread sheet.  Then I have 13  
columns which represent  13 weeks (1/4 of a year).  Each week there are 6
people assigned to be moderators and I place the letter M in 6 different rows
within the column for the specific week.   I also put other letters within
the columns to alert me as to who are participants vs moderators in any
individual week.  If I want to generate a list of the 6 moderators each week
is there a function I can use that will identify the 6 row numbers that have
the letter M in them?  Then I can use those row numbers to print myself a
list of the names that correspond with those row numbers.

My final goal is to be able to generate a list that will have 13 weeks down
the left side and to the right of each week number will be the 6 names of the
moderators for that week.  Essentially a schudle for a quarter of the year.

Thanks
Carl
