This is a small easilly editable script which can rotate user's adverts in the channel and will rename them if they chhange there nick and will also turn off if they leave or disconnect.

The t.set alias allows you to edit the text it says and the theme alias allows you to change the colour of the text.

Commands
!timer on <ADVERT>
!timer off [nick] (Nick is ops only)
