Staff and students in our school have lost their clustrmap and other widgets from their blogs. To restore them, follow these instructions:-
1. Login to your globalteacher/student account
2. Stay in the dashboard
3. Goto plugins, on RHS between links for settings and users (on the same line as write manage design comments)
4. Scroll down until you see the widget pack
5. Tick the check box beside the widget pack, choose activate link
Widgets should now appear.
nb There are some nice new plugins available eg social bookmarking
Thank you for putting this post up!
Other posts that I found that dealt with teaching how to put up Clustrmaps I found very confusing, but yours really made it short and sweet.
