A booking system for is something that I have been working on, off and on, for a couple of years.
The problem(s) that arise are simply that a booking system is more of a web app than a stack.
While, I have had success in my personal tests with a series of stacks that essentially let you build a booking system wrapped in a RW theme … It would be, IMO, a support nightmare.
It would involve creating a mysql database, installing a table into that database as well as some other info that would be unique to each user.
Having been in the RW Community for 13 years now, I know that there is a limit to what the RW Community is willing to pay for a product, regardless of how good or helpful it is. Releasing a booking system would appeal to such a small number of people that it would likely be cost prohibitive.
How would you feel about some videos showing you how to install a 3rd party booking system in a RW project?
Or are you wanting something that was designed specifically for RW/Stacks?
