I've no idea how to code an application so this is a suggestion rather than volunteering myself!

It'd be cool if VG Chartz had its own Facebook application which let you display your games collection like you can on this site. There are a couple of apps offering a similar thing but they look rubbish and only display a few games at a time. If the VG Chartz app showed the whole collection but with smaller boxarts than on here it would be a great thing to stick on the bottom of your Facebook profile. It would also be great advertising for VG Chartz.

Is anyone capable of producing this?

It has one (or had one) and it completely sucks. Just like the VGC banners are very updated and completely suck.

Do you mean the group? VG Chartz has a Facebook group with 35 members. If there's an application it's not showing up in searches.
