It is easy enough for any person with little or no experience in managing an event of this scale to use it effectively. I have found that there are many features available which make Eventmaster very flexible. The interface could be improved but the support team has been extremely helpful over email when we've needed assistance. There's nothing really bad about EM as such - just some minor feature improvements would help us get more out of our system. We're using EM to run several large conferences per year for various clients. This includes both virtual and physical events. As well as being able to create tickets and delegate tasks through the software, it also allows me to keep track of all my client contacts via their profiles.
