Hi – great questions!
I purchased the pro version because of the extra data fields. I successfully logged in and created the fields needed for the event. How do I add custom fields for the venue?
Additional fields (in the PRO sense – ie, offering different types of field like radio buttons or text fields, etc) are not available for anything except actual events. This has been suggested as a feature request and you are more than welcome to up-vote the idea and add any further comments 🙂
Also, I was disappointed to find out that when I imported the event data, I couldn’t map the fields in the csv file with the new custom fields I created.
At this point in time it is not possible to import additional field data by CSV. It is a fairly popular request that is already under review, though, and as before I’d encourage you to up-vote the idea (and comment if you have any further feedback to add).
I hope that clarifies things, but do let me know if you have any further questions 🙂
