webinar calendar and sign-up

I receive a monthly email with a webinar calendar but find it hard to sign up:

1) Is there a direct link to an online calendar with webinars?

2) Could it be made easier to sign up for multiple events, e.g. by clicking a box or by prefilling the fields when you are logged in? Currently we have to fill out all data (name, email, business, phone etc.) for each individual event.

Thanks.
