Hello, I am loving the WPMU plugins and I’m trying to pull off a pretty different site using some of the plugins here. Basically its going to be Trip Multisite website with each child site being a separate trip. For that trip, I want to add products (which will be people traveling on the trip) and allow people to make donations toward that particular individual’s funds.

I don’t see any donation functionality in the Marketpress plugin. Are there any ideas, workarounds, or other plugins that could make this possible? I basically want to allow the user to enter whatever price they want to pay. Thanks in advance,
