So a year and a bit after writing this script I'm still getting the odd kmail from people using it, which is nice
The new update parses stuff that can be zapped (and non-tradeable outfits that can be zapped) from mafia's data files, so the script won't need updating as new stuff gets released.
Thanks. I use it daily. If you are still interested in tweaks, I stole and reworked the code that checks Coldfront and called it CFStat. Retrofitting it back to Zapwizard has been on my to-do list. Only benefit to that is it gives ZapWizard and other volume checking scripts a common cache file, which they don't have now, but that, in turn, has the potential to reduce hits on ColdFront.
