If you want to change your SuSanA user name for whatever reason, please send an e-mail to the secretariat (This email address is being protected from spambots. You need JavaScript enabled to view it.) or to me. It's easy for us to change it. You cannot change it yourself.
For example, I have changed mine today, from "muench" to "Elisabeth" because sometimes people addressed me with "Dear muench" so I thought it's time to change it - after 9 years and nearly 3000 posts...
