I'm not sure if anything exists, but I'm trying to figure out a way for my wife and I (or more) to utilize a web-based calendar system.
We both use Windows Live Mail, so my first guess is that we use that. However, my guess is that if I set up her account to use my login, she'll get all my contacts as well. I don't know if windows live calendar supports multiple shared logins.
Maybe there are some options with google calendar? However, I'm finding it hard to 2-way-sync google calendar with windows live mail.
I also host my own web server, so if there's anything that I can download and run myself, that's an option as well. Any ideas? Thanks.
