Grrrrr! I emailed them about a transfer and they told me to log in at 19:00 on Wednesday last for the 10 remaining transfer places. Lots of re-loading on the Tri-Ireland site and boom, the enter button appears! Happy days... not!
I'm in! So I filled in all my details for two places and the TI site has a brain-fart. No session cookies, no re-loading, page gone, places gone, enter button gone!
