What would be the path to upgrade 2.0.9.1 to 2.0.13.2? Do I have to install each incramental patch from 2.0.9.1 all the way up to 2.0.13.2 in order to get there or could I just dump 2.0.13.2 in and have it work just fine?

Thanks!

Also I ported an app into XOOPS how do I go about offering it up here for others to use?

Quick answer is that you must install each upgrade incrementally in order to upgrade Xoops. Do that and all will be fine.

Just a side note - when I did the same upgrade I had a problem with custom HTML blocks vanishing. This was being caused by custom templates not being updated. This problem was solved by updating the system module and then regenerating system_block_dummy.html and system_block_online.html

Second question, I don't know the answer but i'm sure a lot of other people round here do
