To find out what stairs you can currently challenge someone in, first go to the Main Stairs Page, then click on "Show your stairs only" link. The ones in BOLD are ones you can make a challenge in. .
Fencer: ohhhhhh: after i click "Stairs" i have to click "Show your stairs only" before i see which ones are bold (like rod said). i forgot about that - i thought i should see my stairs in bold when i just clicked "Stairs" in the main menu. it would be nice if i did, hint-hint...but this'll work for now. ;) thanks, Filip.
rod03801: you can find a server at the mall if your mall has an Apple Store. a low-end Power Mac G5 plus the server OS will run you about $2500.00 US before tax.
