* may want to record these numbers in table above at the end of the year b/c didn't see way to look at numbers from past years

Mailing List

last updated Feb 29 2024

There are 3,717 freesurfer mailing list subscribers (includes those who do not receive messages but can post).

To determine this number, login to the administrative interface of the freesurfer mailing list, click 'Membership Management', and the total number of users is shown italicized in the middle (just above the letters of the alphabet). This number includes those who have opted to not receive the mailings. To subtract who has opted to not receive emails, each of the 20 or so pages of the membership list must be checked (tedious, but this takes about five minutes, versus trying to figure out how this info is stored in the bowels of the mailing list server).

To count the # of emails, what I did was go to the mailing list archive here, copied all emails from a certain month, pasted them in an Excel spreadsheet and looked at what # it went up to. I'm sure there is an easier, more automated way that could be developed.
