MACRO

Hello,

I have never written a macro but lately I have come up with an idea for one. I would like to equip certain outfits and trinkets as I press the "mount hot key" and to unequip those outfits and trinket (/swop back to the normal gear) as I dismount. I'm sure someone must have thought of that before me. Can anyone help me getting started? Or give me the address to a good wow-macro-website?

Thanks
