Well, as you can see I am still messing about with the theme, but I've finally upgraded from b2 to wordpress.
It was about time, wordpress has tons of improvements, and it is mantained. Sure enough, my customized version of b2 had custom fixes made by me for comment spamming and the like… but still is nice to run on an actively developed platform rather than on an abandoned one.
Of course one side effect will be that my custom permalinks (archived by google & c.) are now broken
Maybe I'll figure out a way to configure BOTH wordpress mod_rewrite rules AND my own old ones…..
