Minimum donation value

I would love this feature and I am willing to contribute code, if developer(s) could step out and give some pointers to code.

I am really in need of this as well...it would be great to add a minimum donation amount so users could not donate more than paypal processing fees while maintaining the right to donate whatever value they wished.

Bump. This would be huge for me and will also be willing to offer time to get this feature implemented..

Ditto.

Double ditto :D

This is something I am needing for a Non-Profit client. I will be working on a solution tonight.

A temporary Ideas for handling this is:
1. Setup a Conditional Action that is triggered whenever a donation type Product is added to the cart. Then Have it check the donation value entered and the sell_price for the product. if the donation amount is smaller than the sell price then we post a message and let the customer know what the minimum is.

Here's a patch to the validator functions. It's a simpler solution than cmcintosh proposed, but in my preliminary testing it seems to work fine.

I'd love to see this feature as well. Might need a bump - still waiting for review.
