Thank you and try to get back to me by Friday, May 11, 2007.

Hello,

I tried accessing the link you posted, but it requires a user password. Additionally, although there are many scientists and student volunteers who answer posts, not all will be answered in within a day. Please, if you need an answer before a certain day, try posting a couple days before, allowing experts to post back.

Sincerely,
Sareena
