Modifying Votesystem

['LinKin]

Hi,

As all of us know, the votemanager displays 9 options to choose.

1..8 - maps

9. Play again

Can someone tell me where to modify it so that the votemanager displays the following 2 options:

1. Random

2. Play again

And also, how to set a map limit count so that it cannot be played again more than 3 times in a row.

Thanks
