No problems updating the Siblog to WordPress 1.5 …. I managed to retain all mods with no problem. With any luck the spammers will be frustrated further.
While I was at it, I’ve updated Sibagraphics and client forums … slightly more complex but very worthwhile. I’ve also implemented some considerable css compression by (1) converting all hex colours to shorthand names eg. #003366 becomes #036, and (2) including line-height sizes in font styles eg. font: italic bold .75em/1.2em verdana, sans-serif.
