No need to be nasty. You have no idea who I am or what troubles I have. If found that remark to be unnecessary.
The recommended way to can IS to leave the rings on the jar. Jostling jars on the shelf can cause them to come unsealed. Improperly sealing a jar can cause the food inside to rot, popping the lid off also - that's quite a mess on a shelf.....
I wasn't being nasty. In fact, I realized after reading my post that it might come across that way, so I took the time to amend my comments to be clearer.
In terms of storing jars with the bands on, that's just not the recommended method at all--by anyone. If your jostled jars come unsealed, then the seal wasn't good to begin with and be thankful that it did come unsealed. You should be able to hold a full quart jar by the lid if your seal is good. Secondly, screw bands mask a bad seal. If you have a bad jar of food, it's better for the lid to pop off early in the spoiling process as gases start to build up, rather than being held in place by the screw band and building up to the point at which the lid explodes off or the jar itself explodes. Third, rings that rust can cause seals to pop and the best way to rust out your rings is to leave them on jars. The only purpose of screw bands is to hold the lid in place as the seal is forming in the canner. After removal, bands should be washed and dried before storage. I store mine on a clothes hanger--just pry open, slide the rings on, then hook it back shut. Cover with a plastic grocery bag tied at the bottom and hang.
Here's some info:
"Should screw bands be left on jars of canned foods during storage?
Jar rings, or screw bands, should definitely be removed before storing jars because some spoilage organisms produce gas causing the lid to swell and come unsealed. If jar rings are removed before storage, it is easy to see if lids have come unsealed. Additionally, if enough internal pressure is present and rings are left on, jars may burst. Remember not to remove rings or disturb jars in any way for 12 to 24 hours after heat processing. The vacuum inside jars gets stronger over the 12 hours after heat processing. Leaving the ring on during this period helps the vacuum form."

"If sealed, carefully remove screw bands. If a band sticks, loosen it by covering, it for a moment with a hot, damp cloth. Bands left on jars during storage may rust, making later removal difficult."
National Center for Home Food Preservation:
"If lids are tightly vacuum sealed on cooled jars, remove screw bands, wash the lid and jar to remove food residue; then rinse and dry jars."
Lancaster County Extension Service:
"Remove screw bands from jars and wash jars before storing. Properly sealed jars do not need the bands on to hold the lids in place. Screw bands can rust if left on the jars in storage causing the seals to break."
