A huge update to the forum software will be released December 21st. It will be a major change, which means the style and all the previous modifications will have to be customized again. A lot of bugs and probably some downtime can be expected. To start after Christmas some time.
I'm thinking about removing the Wiki, as it's very rarely used, and not 100% compatible with the forum. The SEO software will probably also be removed, as the new forum software have something built in. It will however mean that old links to threads will be broken.
