I'm trying to develop a fundraising site using paypal using wordpress.com. However, I cannot find anyway to add custom, 3rd party widgets to the blog. In Particular, I want to install a paypal donation counter widget. As far as I can tell, wordpress.com does not allow this - it has only a small selection of widgets which can be added. Please assist.
The blog I need help with is evagoestocollege.wordpress.com.
