Demo
Look at my b2 blog.
Direction
1. Download this file first.
2. Unzip and open b2archives2.php in any text editor.
3. On line #14, replace http://yourdomain.com with the URL of your blog with No trailing slash after (/).
4. On line #16, replace b2posts with the name of the table for your b2posts. If you don't know, download your b2config.php and look at the line #64.
5. On line #18, replace 2003 with the year you start blogging on b2. If you want to include the previous entries that you blogged somewhere else, you have to transfer all of them to b2 first.
6. Save file and upload it to where your (b2) index.php file is.
7. Point your browser to http://yourBLOGurl/b2archives2.php.
8. If it's working fine, now you can edit the template (just like when you edit the main blog template).
9. Rename b2archives2.php to b2archives.php or any name you like.
