Good luck for your up-gradation. I like your new forum software. But I have noticed that the older forum is not turned to read only mode but its url will redirect you to the new domain of the forum and everything is available there. by the way that is great.
I am asking a personal question that is that the software which bitcointalk is going to adopt in the future or it is your own custom software for your forum?
Sorry for the late reply. The forum was originally placed into read-only mode, but then the forum admin started redirecting the old domain. We're still trying to sort out a couple issues with the redirection. If anyone wants to visit the old forum, it can now be done at the following link...
