Plugin for users to store data?

Hi all,

Does anyone know of a plugin which will enable logged in users to my site to tick boxes (or something similar) and for that information to be stored for each time they login, manipulated, etc?

What I want to do is allow users to perform a set of tasks, and tick each one off when they have done it, so that each time they visit the site they can see what they have left to do. Also, I need to be able to add new tasks as they come up, and for them to appear for all users. It’d be nice (but not essential) for them to be able to enter a figure (how much they made on each task) which is added up so I can then do a ‘top 5’ list.

Any ideas anyone?

Thanks!

J
