I am opposed to putting membership information on the web, period. Even if protected by group access, even if protected by password. Hackers can still get in if they are persistent. Information that is appropriate for a website includes the guild's meeting place and time, schedule of upcoming speakers and classes, newsletters, etc. My local guild also had the names and email addresses of the key officers. The treasurer received an email from someone claiming to be the guild president, directing her to send a money order (several thousand dollars) to a "vendor." She recognized that this was a scam, and personal email addresses are no longer on our website. Who would have thought that quilt guilds would be the targets of scammers?
