I've found good replacements for most of the forum functionality we rely on so think we're close to ready to make the move, but just have a few questions remaining from my initial post.
Allowing users to see their own deleted posts, we did a code modification on vBulletin, but haven't been able to find a way so far of achieving it with XF. We find it a good way of communicating with members to have their posts/threads not just vanish.
Likewise, is there an option to name the specific moderator on an 'edited by' statement. Again as it allows users to contact the moderator that acted on their post directly.
And can someone assist in getting our vBSEO urls converted over to Xen?
Thanks again for everyone's help - spending the time looking around here has solved the majority of the problems and has me quite confident in pulling off the move successfully.
