Q:

Where to put a specific question:  online banking program (Jameica/Hibiscus)

I have a Question about a specific open-source online banking program (Jameica/Hibiscus) and do not know where to put it. I have browsed the StackExchange network and, even though all portals are categorized and neatly displayed, by now there are so many I felt a bit overwhelmed.
However, I don't think any question about that tool has so far ever been asked on any of the portals, and I wouldn't know where to ask.
Is the topic no suited for the Network, because it is to specific and there's possibly not enough user-base interested in the topics? should I resort to the official forum of the tool?
If not, if there's something new that I don't know, how do I proceed?

A:

If you're working on the code for the program, put it on stackoverflow.com . If you're installing it, then probably webmasters.stackexchange.com.
If you're just a user of the program, then superuser.com if it's a desktop app, and webapps.stackexchange.com if it's a web app.
