I have about 10 seconds of empty space at the beginning of my project. Is there a way to move the entire project in one action, rather than moving each clip one at a time - in order to get rid of the space?

Oh, Vegas 8 Pro.

ctrl-a (select all), drag

Double-click the empty space to highlight it.
Press the DEL key followed by pressing Ctrl+Shift+Del (Post Edit Ripple).

Thanks. This helps.

OR double click in empty area on 1 of the tracks. Control X then F will post ripple all tracks to the left. empty space begone! ;-)

FYI - the first suggestion worked, then second one wouldn't. I haven't tried the third next - I will the next time I need to do this.

check the tool bar. You may have all of the or at least some of the ripple edit turned off.
All of those methods should work.
