Skype
General
It depends on the layout of your site, it was originally used in the sidebar of a support profile page.
I don't have any screenshots - this module hasn't been in use for 8 years or so. It may not be in a working state.
It wasn't intended to be used on all profiles, but it does depend on your network.
Yes, but you would have to check each skype name in your smarty template. Probably easier to vary the position by quota rather than smarty name.
