Wow! What a difference a few hours make.
Just spoke with you earlier this morning. I had absolutely no idea you were considering migrating your board to Xenforo. I was actually hoping to get to work on your project soon. Holla @ me if I can be of assistance to you
I'm on a lot of aquarium related forums and almost all of them run vB...for now. I try to contact the staff whenever I can and prop up XF. I've got at least a few interested
I saw your thread on TAZ and I think you've made a good choice; you'll hopefully get a much better official support response here, and the community members are very helpful and knowledgeable too - so ask away.
I find this software to be really good to use and a bit easier to use. With vB I found it difficult to do a lot of stuff but I know it's going to be great to use as a back up software.
