"The methods currently in use - capitalizing the last name, a picture of a tree, etc. - work fine for some, but create extra work for those of us who have to change the caps if we get info from another tree."
What other trees are you getting info from? Are you copying from those shaky leafs on Ancestry?
You should be keying-in all your info to begin with. This prevents duplicate profiles and a lot of other garbage you'll be spending time cleaning up in the future.
The reason a standard method works for "some" is because "some" understand the Ancestry Member Tree program is more of a display than a full blown genealogy application. ACOM trees may not be around in 10 years, so if you value your work, you have it on a desktop application. There are many desktop apps, and they're not uniform in their formats.
