Adding a Checklist to the Site

[TheImpCaiman]

Not sure if this has ever been discussed or if there is a way of doing this. Is there a way or a way that can be added for us users to log in and check off themes in our own collection, and possibly have a way to show everyone else either how many we have in a count or what we have. For example I would log in and perhaps under the themes or something I'd scroll to a theme I have and place a check in the checkbox that I have a copy of that theme and it is saved to my profile. Then others could see which ones I had or just how many I had. Has something like this ever been discussed or thought of before? It would also be neat way to track what I myself am missing and still looking for. My Excel sheet is getting a little tough to track.
