When upgrading to Event Espresso pro...they charge for any little thing. Worst is the pro edition is not ready for prime time. Lots of bugs. Constant updates.
When you purchase the plugin you assign a domain...well they dont tell you but once you want to reassign the to a different domain they charge you $10. WTH. I never experienced this.
Its a powerful plugin but has a small dev team that isnt ready for prime time. Dont waste your time on this. Im moving to a different event manager after I spent over $150 on their business license which is only good for one domain. Total ripp off.
