Most of these things will be possible in a few months. We are reorganizing the Nabble code so that users can change the UI the way they want. There will be templates, themes and designs and an API for module creation. Having an installable Nabble is also in our plans.

I must admit that I had previously installed Nabble in haste and had not done the due diligence. That being said, I would like to examine the scenario that I want to migrate from Nabble to another forum software. Is there a way to export data (including messages and users), preferably to a suitable format that allows easy importing into another popular forum (such as phpBB or SMF, etc.), or in a more general format such as XML, CSV, or (at worst) a raw database dump?
We can export to XML right now, but this isn't easily imported by other forum software. We may work on this in the future.
