Tim sent this to me -- and I betcha to others, too.
"Hello All,
Registration is now open for this year’s events. A few people reported a problem with one of the PayPal buttons. I reinstalled them so they should be fine now. If you are still having a problem, make sure your pop ups are turned on and then try Internet Explorer if you are using Crome. Hope to see you all this summer.
All the best
Tim
