Can I just say it will be a welcome change. This site has it's pluses but not as many as the minuses. It's antiquated and as mentioned in the other post no longer supported which leaves it and the members open to potential hacker activities. Can you share what platform you are moving too or testing?
I also saw a comment about URL's and if converted properly all links should properly resolve to the newly updated URL. I can't wait to see the new site and only wished I was part of the transition team. Cheers!
