I'm posting this here because it's trivial and doesn't need to be crapping up the other forums. A simple enough thing: what does "fopnu" mean when it's un-acronymed? Anyone know? (well, I know the creators know, but no need to bother them with it if someone else knows) Oh- and in case this has been answered previously, apologies, but I don't know how to do an in-forum search (when I use the search box, it takes me to google - barf)
BTW, been using Tixati for years, it's truly the best (even though my understanding of it is minimal) and am happy to have made my first donation today. Thanks for the great work, Devs!!

I think it's based on a simple pattern hiding in plain sight.

Look at the letters in TIXATI.  It's all straight lines, no curves.

Look at the letters in fopnu.  All letters contain curved lines.  Also note that fopnu is spelled out in lower case in the logo.  

Coincidence?

Thanks OP for the support!  It really goes a long way.

The last reply about the origin of the "fopnu" name isn't too far from the truth.  Also, it is hard to get 5-letter domain names, and I wanted to keep the name as short as possible.
