Hello Steve,
After spending some time with the software and trialing it out with live events, I will have to say that I have wasted my time with Social Booth and that DRB is a far more superior software than Social Booth.
Reason for stating this is that for a graphics point of view, DRB is the best solution, it makes it easy for users to style and customize the theme/layout, there are a lot more controls and functions, it is thorough, it has more features that make the whole process easier.
DRB also uses less resources than Social Booth. I would like to talk to you about possibility getting a few licenses next year when our new booths are built, but for the meantime, did you have any sales for one license coming up as I would like to purchase a personal license.
