If it looks a lot like the old one, well, that's because it's supposed to.
There should be no visible changes to the forum or any other files on the www.photomacrography.net site.
Besides generally faster response, the only thing you should notice is that the address bar of your browser now says "www.photomacrography.net" instead of "www.photomacrography2.net".
If you have any offsite links that use the old "photomacrography2" name, it'd be a good idea to get those updated sometime soon before you forget about them. We're currently automatically redirecting www.photomacrography2.net to www.photomacrography.net, but that's intended to be a short-term transition tool.
Anyway, we the admins sure hope you like the new site as much as we do.
All the best, my friends -- and keep those macro/micro shots comin' in!
