This move is about modernising a bit. A lot of this stuff was discussed in this thread:
I'll quote myself there:
We have thousands, yes thousands, of users on the forums that don't interact. I tried to limit it but I transferred thousands of dead accounts? Why is that? Surely we could try to improve that situation. I could have just moved the old forum and let that all be, but I'm trying to improve things where I can.
This is all about moving things forward and improving engagement. vbulletin hasn't been updated in years. The problem is the negative voices are always the loudest. It really is a lot of work moving things forward here.
Yes tapatalk doesn't work with the new forum. There are guys working on a tapatalk plugin for this forum and probably also a discourse app. This forum's mobile site is really good though. And makes it easier and quicker for new members to engage.
The reason it's locked is to at least get people to try the new forum before shouting at me. I did do a lot of hard work on this and I want to take it further by integrating WIND badges and WMS badges and the like. And people can at least try it? Is that so wrong?
Plus it makes everything complicated if people are replying to essentially the same thread in two different forums.
