Change your address "on line"
Or E-mail changes to email@example.com
You will need to include the following:
1. Your name.
2. Your member number.
3. Your old address, include your phone number and your E-mail.
4. Your new address and any changes in phone and E-mail.
5. Include any other changes such as company affiliation Ect.
(Editors note. I have used both means to change my membership data. I find the E mail easier)
