A lot of changes will be made to the whole of unexplained-mysteries in the very near future, including a variety of new features and a new navigation system to help you get around. A lot of the new features have already been completed behind the scenes, and will appear before too long.
An example of one of the new sections to be soon introduced to the site, can be seen by clicking this link. This yahoo-style links directory will replace both the search engine and links exchange, offering a variety of site links for visitors who are looking for specific subjects. At the top of the page, is an example of the new site navigation system, which will provide a clear and simple bar of options for getting to any site section from any other.
At the moment the directory is pretty much empty, but I will be transferring the search engine and links exchange entries over very soon. If you have a web site, or know of a good unexplained web site, feel free to use the "add link" option to submit it to the index.
