I like that it's easy to use, simple but effective (and free!), has many useful features which are very user friendly for my needs! It is not difficult at all - you can learn everything in few hours of usage with some practice :) Nothing as such because there aren't any problems i dislike about this software so far ;) The only thing maybe could be improved was when adding new member into your group they don’t have option "add profile picture now" or something else if needed :). Great way how we organize meetings/workshops where everyone knows each other already from previous events organized by us before using meetvibes platform!
