Just to clarify, do you mean only the site admin can place content inside the widget - which will then appear on everyone's profile - or the widget will only appear on the admin's profile (and therefore invisible to all other members/non-members)?

Hello,

appear on everyone's profile. But, only the site admin can place content inside the widget. 

And is visible for member and non-members ...  like any other widget.

That's all :)

And, of course is translatable. 

Cool.  Thanks for the quick response.  Could be a good way of placing ad's on sites, but will need to test it myself first.  Nice idea though... :-)

Can this plugin be used more than once? If so what needs changing, other than the html, of course?

@Burgs  No. Only you can create new plugin for new widget.  Its easy. Change name of module. 

I'm sorry, I don't understand well from where the content comes. how can I change it and edit it easily when I want?

Thank yo for the widget. Simple but very strong!
