We have been using e-days since January this year, and are very happy with the features and the flexibility of the system, which has allowed us to implement a few tailored settings. The support team is very responsive and helpful, and the whole set-up process was managed quite efficiently.
I'm looking forward to exploring more functionalities in the future!
My only suggestion would be to increase the webinar sessions, or allow for more people for each of them, because it happened already a few times that I would click on the link from the email notifications soon (within 5 minutes) and the sessions were already booked up - which I assumed it's because there are only a few seats available.
