Yes we provide all support for our themes via the AppThemes forums, with a dedicated support team available to assist customers with theme related questions, as well as an active community. The forum software allows you to configure your own notification options, so if you wish to be emailed whenever someone has responded to a post, then you simply choose the frequency of these notifications.
This section of the forum is "Pre-Sales" because it allows potential customers to ask theme related questions before purchasing. I assure you that there are human beings checking these forums and responding to questions ;) You can read more about our support hours
here.
If you have any more questions/concerns, please feel free to ask away! :)
