I have a facebook.com account and a myspace.com account but I don't know where to add the widget, some help please.

go onto my home and then account and you would find it on a tab on the outside

Can't find it

You can find the page of widgets here: http://www.chess.com/widgets/

I had placed the widget on my blogger page and it is great to have it there.

I can't find where and how to put it onto myspace.
