Just as Wikipedia does, Yahoo! have offered with it's MASH community the ability to edit someone else's profile, as well the profile-owner's ability to undo any changes made to the profile. This allows for a more interactive community as people can go to other's profiles and add content, change the layout, or add some funny images to the page.

As well as this, Yahoo! have also offered us something they like to call a MASH Pet. With these MASH Pets, users are able to look after and care for a little pet (by default it is a quite strange looking face, but users can change their mash pet if needed.) by feeding it, petting it, and for the meaner of people out there, by smacking it.
