Calendar tweaking and options

[FearlessWeeder]

This is our basic calendar. I think it comes with vBulletin.

First, we'd like to be able to remove members birthdays. How do we go about doing that?

Second, the events that have been added to the calendar do not appear unless one is registered and logged on. We would like the events to appear to guests. How do we make them visible to those who are registered and logged on as well as to guests?

Third, the basic vBulletin calendar is too basic for us and the entries are difficult to read because they are all scrunched together. Are there other calendars to select to use at our site somewhere?

This is an example of a calendar that seems to have more space-

And, their events are clickable in that when I click on something I am interested in, I go to another page that provides more information on the event. How do we do that?

If I have not worded this properly to be able to receive help, please let me know and I will try to re-word things differently.
