Mines organised into separate lists for each area I visit and could realistically punt. I keep little reviews of each girl in the notes section along with a phone number and address usually.
I normally set up a temporary list and play a little game I like to call "prossiebay" rules as follows...
Find some shite on eBay you could justifiably purchase
Get the address for collection
Search out the local talent
If the talents talentless then don't bid
If the talents good then bid
If you win the auction you get to treat yourself to a collection day punt as a prize!
