My organization occasionally does one-off fundraising drives for specific situations where we need to raise a certain amount of money (e.g. "Send our youth employees to the US Social Forum"). Creating a new contribution page makes sense here. But we'd like to have a thermometer on the page.
Using a personal campaign page would give us a thermometer, but it's an extra hassle to set up, and doesn't quite fit the situation as well because of the way the PCP creates soft credits.
The contribution page provides a widget with a thermometer that I can embed on other sites. I can even embed this widget within the contribution page to obtain a thermometer. But then I get a bunch of superfluous stuff in the widget, like a "Contribute" button which takes people to the page they're on. No good.
