That's a shame, as one of the threads I saw mentioned something about the xenforo converter for vb3 taking four days to complete, and CLII importer for $150 being offered. I have no idea what CLII is, but it's obviously over my head, and I would resent being charged $150 to become a customer - or wait 4 days for an upgrade script to complete.
Which is a shame, because it seems like the vbulletin customers have mostly fled to Xenforo - and this community appears very active. Whereas the vbulletin forums are very quiet, and I am still waiting after 3 days for a "Professional installation and upgrade" from them.
