php shared event calendar suggestion

[Jon Moss]

Does anyone have any recommendations for a php shared calendar (preferably
with user authentication)?

For the church website, I have a message board (phpBB2) and online photo
album (phpwebalbum) but would really like a shared event calendar that at
the very least the team leaders could post events to.
