I've just got some questions! Currently, my site is running vBulletin 4.1.11. I am aware that the vBulletin importer for vB4 is not official but I'm hoping it's alright to ask these questions in here: Visitor Messages: will they be preserved in updating? Private Messages: likewise. Post Formatting: how broken can I expect it to be? As in, if I made this list in vBulletin, would the BBCode translate over to Xenforo? Avatar Size: Would it be possible to allow avatars of different sizes in the member info blocks, at the side of each post? I realize that Xenforo was going for a uniform approach and this would defeat the purpose, etc., but I'm curious. Navigation: is it easy to edit the top navigation bars? I played around with a demo for a while and didn't come across anything, but it is possible I just missed it. I am fine with using HTML if I must, but having some sort of Admin CP option would also be nice. Moderators: We have two sorts of moderators, ones that have power in only certain sections and other, global moderators, who also have power to ban. Is this possible in Xenforo? Sorry if these are obvious! I've been sniffing around the site for a while, and did play with the demo. I don't expect anyone to answer all of these, but anything is appreciated! Thank you!
