Hi Molly,
Thanks for posting!
Virtually all of our support and all pre-sales enquiries are handled via the forums. I definitely appreciate live chat or even a phone-based conversation may have more appeal but we don’t currently offer either option (and I wanted to emphasize that, in case it is an important factor in your decision making process).
In relation to spam-fighting efforts, besides having an option to save new submissions as drafts (allowing admins an opportunity to vet them), we additionally now offer direct integration with reCaptcha which greatly reduces the likelihood of spam getting through.
Let me know if you have any further questions 🙂
