Issues with Registration in a school

Hi
I have 100 students playing chess for just 8 weeks
However, when they try to register the captcha doesn't always show - so that means they cannot register
Any ideas what we are doing wrong

I sometimes feel the Lichess site cannot cope when there are dozens of students trying to register at the same time

Great site though and a great way to learn chess

@Baysgarth_DOR write an email to lichess about it and they will allow more requests that works for schools and via lichess class
lichess.org/class you can create accounts in mass
