Skinning the board has been extremely easy, easy to find things, easy to edit things. The style there only took me roughly 5-7 hours working on it while being distracted with a movie and kid to take care of.
Everything I've encountered so far is extremely self-explanatory, I don't have too many questions and when they I do I can find the answer on these boards as it is.
I know there's misc bugs that people are finding but so far I'm bug-free that I can tell(I know they exist just haven't run into anything major).
But overall I'm estatic to see where this product goes, I'm amazed that 2 days into it launching there's over 15 mods and styles, a wordpress bridge(haven't tried it yet) and many other promising things coming. I'm glad I purchased my XenForo
I've also released that style for licensed customers here
