Upgraded this site to B2 v0.6pre5 of the B2 blogging software, new features such as PingBack and TrackBack, which up till now I do not know how it works.
Here are the main features:

» TrackBack support (not MT’s standalone trackback)
» Pingback support: Pingback is a new way to put the ‘web’ in ‘weblogs’, as it allows your blog to automatically notify other pingback-enabled blogs that you linked to them in an entry
» some new template tags
» many bugfixes
» and many more other stuffs.
