Hi guys, I’m not so sure if this was the right section to post this but I needed some help for a friend in uninstalling Semiologic pro from his blogs. He doesn’t have access to their forums since he only got his copy from a friend. Please help.
All help is appreciated. Thanks in advance!
(Moved this to the WP forum for you) 
Been a while since I last looked at the semiologic theme - but this is just a theme for the site, right?
Getting rid of it then means you just need to select another theme to work with from the control panel - then you can delete the theme files from your server if you want too.
