Review on DiscourseHosting by Christopher Gulledge

It's easy to get started, it has all of our features we need (including multiple domains), their support team are helpful if they can help you at that time but not pushy once they've helped - just keep going back! Their prices have gone up recently which means there aren't as many people using this service anymore so I think its value for money isn't quite what it used to be.

If your looking for an inexpensive way then perhaps try another option first? Our customers love being able to communicate with each other in realtime via threaded comments rather than emails or waiting until after hours/days later when someone may well forget about something posted by them months earlier.
