Great news: the MB mailing list that's been around since the 1990s has been upgraded to new software. Anyone on the old list will be automatically added to the new one; if you're not a member and would like to join, you can do so at this page. Thanks to Thomas for the smooth change-over.
You can also add yourself to this map, and see where other Modesty fans are located.
In addition, you can read stories from Modesty fans about how they first encountered Modesty, on my website. Please feel free to contribute!
