I'm working on the test forum now on my own PC, trying out ideas and the new features. It's going to take about a week before it's ready to launch, but once it's online it may take a couple of days to get the full funcationality back (I can't do it all on my PC and them move it, as I can only take a snapshot of the post database - and I don't want to lose any posts ;)).
The gallery is going to be upgraded to a new version that works much better, the excellent database section is going to be given a facelift to make it easier for John to edit and give it some extra prominance on the site :) It's going to be quite a big change, but it's needed to make sure that we are the best reefs forum on the planet :D I'm really excited about getting the new changes online.
One very visible change will be in the forum categories, as there are some sections which overlap at the moment (such as the 2 photography forums). There's going to be a big move around of forum sections, the biggest change will be splitting "Reef Talk" to be it's own section containing several categories (including the existing Fishes, Inverts and Coral categories). This means that there won't be any confusion on where to create or find a thread, as some threads could go in many forums as it stands. I really think this is going to be a great change, as we'll have a forum that is easy to navigate and has some great new features.
Other things on the way are calculators (for salt levels, water changes and many other things)... you guys are going to love it :D
