For a long time, We (The Bilbo team) and KBlogger developers were in touch to replace KBlogger with Bilbo and put it into KDE PIM as its primary Blogging client.
And after last release (a.k.a Bilbo 1.0), We have decided to do the job, So we moved the source code to KDE svn repository.
And recently one member of Tolkien Enterprise contacted us to rename Bilbo Blogger, because it’s trademarked by that organization. So we selected the name Blogilo for it. And from now, We will refer it as Blogilo, And it will be released as a part of KDE project.
