As far as I know, women can be members of MS. We have a female member of the board (Jane Flynn) and have had another, Mary Froening several years ago. In other words, we'll take anyone's money :-)
Seriously, we do accept women as members. We are debating the issue of whether to allow females to post on the male only spot. We have been trying to encourage females to post on the family and friends section of the forum but at times it seems an opinion of a female in other areas is just right.
Time will tell. Please let us know your opinion.
