Help logging in to write a Restaurant review

[Cinderella's slipper]

Hello Dear Magician, ( my very respectful title for those who work computer magic) I read a post on the podcast boards about how to write a restaurant review and clicked on the link that took me to the restaurant review page. Following the instructions, I clicked on log in, ( I was already logged into the boards, and received the error message advising me to recheck the information I entered or register. I knew I was already registered, and I tried to log in several times. Can you help me resolve my log in issues on the restaurant review page. My id is Cinderella's slipper, and I used the punctuation and capitalization to exactly duplicate my screen name. Do you have any suggestions for me?

Thank you,
LL -
