If this is the first time you have entered this MICRSIG registration process, you will need to choose the "Create a new user account" option above.
The password you create for accessing this MICRSIG registration is just for this Seminar and any future MICRSIG Seminars.
If you attended a Microbiology SIG Seminar since 2015, then you have already created an account in the MICRSIG database and can login using those same details (email address and password).
Be aware that this is a separate / new database to the NZIMLS membership system, so your access / membership numbers will not work.
