FAQ on submitting abstract

Cannot log-in.
The password must be exactly same as the one used for your registration.
Even a space before and/or after the password will give you an error message.
Get an error message saying "Only alphabetical character and numbers!!"
This seems to be a frequent problem for those using asian software. Very often, apostrophes and double quotation marks are spelled using 2 bytes (1 byte=8 bits), without your knowing. Easiest solution would be to use only the narrow cursor when typing.
What is the registration ID neccessary for submitting the abstract?
The 5 digit numbers starting with W or J is your registration ID.
