CSS map voting

[Eros Q]

Is it possible to vote for maps in Counter Strike : Source?
Is there any way to predict, which maps will be loaded when? So I can select what maps are to be played in what order.

I know this might have been asked a thousand times, but I'm looking for the answer for 2 hours now and can't find it!

listmaps command isn't in the console and the vote command isn't there either.

Thank you for your answers!

That in the console... if I recall correctly.
I don't know if source still uses a maplist.txt for map rotation. It should.
