BLOG:CMS is the most complete, feature-packed, personal publishing system on the market, developed by Radek Hul?n. It includes state-of-the-art weblog, forum, wiki engine, news aggregator (atom / rss), and photo gallery.
BLOG:CMS is probably the only system that is not only w3c valid, but also ships with application/xhtml+xml MIME type by default, for top performance on modern browsers like Mozilla, Firefox, Safari and Opera. But BLOG:CMS will also automatically supply older standard, text/html, to browsers which cannot handle this, like obsolete Microsoft Internet Explorer.
With BLOG:CMS, you can set up one or more weblogs. If you want to, you can even show the contents of multiple weblogs on the same page.
With BLOG:CMS, you can host discussions to your articles in either your weblog, or in a forum. This gives you much more possibilities and freedom for larger discussions. BLOG:CMS members are automatically registered in your forum as well, and within your weblog you can see date and time of last forum post for each article.
Today, when digital cameras are more common than traditional ones, personal presentation without a Photo Gallery almost could not exists. BLOG:CMS ships with Singapore Photo Gallery, using GD2 and/or ImageMagic to create thumbnails.
Wiki engine is a great tool for any documentation needs, for colaboration on projects. Anybody can add information to Wiki resource. Some of the worlds biggest knowledge resources are based on Wiki engines. BLOG:CMS comes with Dokuwiki engine, one of the best, and standards compliant.
