Self-governed achievements?

I would like to display a list of achievements to the user, and allow them to select the ones that they have completed, applying karma points in the usual way.

We have a project where people have various things they can do in real life (not able to be managed or verified online by any kind of admin). This plugin would be a great way to track those things and assign points to them, if this is possible.

Currently the only thing I can think of would be to use a simple redemption code like “y” or something, and publish it on the page that that is how they “achieve” it. Would love to have a checkbox or something, though.

Let me know, thanks!
