seems to me that you had this page open for too long, it should show the little countdown window with submit button on it
for the pics I guess it's your rank
You are probably right about pics.
About the page, i doubt its too long because i chose BCH and pressed submit in 10 seconds total.
There is a short countdown though, before anything happens, but no submit button anywhere, pic related

Thanks for reply though, appreciated
