I'm not sure just if it is just my browser (entirely possible) but I don't see a donate button on the 'abou't page, just
<form action="https://www.paypal.com/cgi-bin/webscr" method="post"><input name="cmd" type="hidden" value="_s-xclick" /> <input name="hosted_button_id" type="hidden" value="TUTFMERFGV77S" /> <input alt="PayPal - The safer, easier way to pay online!" name="submit" src="https://www.paypalobjects.com/en_US/i/btn/btn_donateCC_LG.gif" type="image" /> </form>
But not anything 'clickable' I'll go in and donate though next week (I hope) once some of my eBay related things have cleared
