Default date in Userform Calendar

In the attached file I have put together a userform that contains a drop down calendar in order for users to select relevant dates.

I have two questions:

1 - I've noticed that from creating the userform (04/01/10) the date has remained as this and not updated to the "current date". Is there any way this could be achieved?

2 - Is there any way the code etc. could be manipulated to alter the dates in the Date Entry boxes, based on that entered into the "Rostered Start Date" box.
I.e. If a user was to select 09/12/09 in the "Rostered Start Date" box, the other date boxes would automatically change to that date.

Thanking you all kindly,

Andy
