The -22F is not a problem, as long as the car is plugged in when left for prolonged periods. At well above that temperature, the battery management system will kick in and heat the battery to keep it within safe temperatures. Now, technically, they could probably disclaim coverage for that, but it seems unlikely if the battery management system does what it's supposed to do.
The $15k charge is a theoretical charge back-calculated from insurance settlements. It does not include any core rebate for returning the old drive train. Since no owner has owned the car for even the current 4 year warranty, we have no information on what Tesla would charge for a drive train replacement, swap or any other non-accident generated repair.
Tape is valuable when you want true off-line backup, that's not connected to a system or powered on at all. Yes, you can do cold backups on hard drives, but they're more likely to fail when restarted after 6 months or longer.
Even in the External Links section? How annoying. Were these general MUD Wikis, or ones specific to a single MUD?
The thing is, if you want, you can setup MUDWiki that has all of this data for all of the great MUDs going back into time. Once you have that site, you can add it as a prominent link on the Wikipedia MUD page. Wikipedia doesn't have to contain every piece of information itself.
