Calendar Program

Does anyone know of a PHP/MYSQL script that allows a user to login and add entries to specific dates on a calendar? Also, to view the calendar a login is required as well. I can do this with asp but it is MYSQL.
Or, can I use ASP code working with a MYSQL Database?

i made a calendar script in CGI/PERL i dont know if you are interested, http://www.tkforums.com/examples/calendar.pl and the admin pannel is not completely done with, because my laptop had to get sent in right in the middle of working on it.

i will not post a link to the admin pannel, because i dont have a password thing on it yet. but if you want to see it, PM me and i will give you the link.

Hope that helps,

PS: you cant see it, but if there is somthign going on on a date, you can hover over the day (it is a different collor and underlined) and it popus up with a little disctiption
