He was last seen Sep 10, which makes it 10 days. He obviously has health issues... which are more important.
I do agree though, in that if he cannot maintain this, that he shifts it off to a competent developer. XF WP integration has really had a positive impact on my community. Google love WP... and users do too when a good layout is used.
Wishing @LPH the best for this health.
I just want him to know, whenever he's able and sees this, that apart from me, looks like there are others too whose business decision to use XenForo was based on the availability of XenWord. I don't think there are any alternatives to XenWord.
