What exit strategy will you provide to your customers when your product is taken off the market by acquisition or simply shut down ? 

People often forget that the true value of forums and other social features is the time the users spend on putting information into it. Sharing thoughts, info and media. Interacting and establishing relationships. The value increase hour by hour and is paid for with the time and effort of your users. Putting all that data into someone elses proprietary software is like giving away the key to your treasure chest to someone else and trusting them forever. You are going to regret it. Unless a viable exit strategy is provided and guaranteed by the vendor. 

Your right.  So then at the very least it should support iPortable. Even with exported data, there is no guarantee you would be able to "easily" walk away and into another forums module if you needed to.  It might work if it was exported in a simple format that other developers could easily extract from. You could provide the source like Mariette suggests, but you would need to be a developer to work with it so at that point your right back where we are now. 

There is so much more that can be developed, it seems like a waste of time to throw it into a module that already exists and that has an active group working on it.  If it's just the email monitor and that is what people are asking for then it shouldn't be too long before that is provided.  No?

If there truly is a gap and people want it then I'll build it.
