Thank you fopr your selfless efforts to the NAFI Master's website. It is a shame that the organization, which has chosen to ignore a significant number of the members, has chosen to ignore the foundation upon which the group was originally founded. If NAFI wants the URL I suggest that you submit a bill to them for all of the expenses associated with your commitment to maintaining the site. As a NAFI Master I personally want to thank you for your honor and commitment to the integrity of the program.
My suggestion (if possible) is to retain the name so it may not be used and forever indicate a notice and forward to whatever domain is established for the new organization.
