Sorry, guys. Stupid question but I don't know the answer. I installed WordPressMU 2.8.4a and selected the blogs-get-a-subdomain-name option only to discover afterwards that my hosting company doesn't accept DNS wildcards. So - if I understand everything correctly - I can't use the subdomain option.
I figured I'd uninstall WordPress and reinstall it, selecting the subfolder option instead. Only problem is, I don't know how to uninstall. I don't mind losing everything connected with WordPress at this point, but I don't want to create any problems with the rest of my website (which includes Joomla, another database, etc.). Does WordPress write to files outside the wordpress_mu folder when it installs? Is there a formal uninstall process? Can I simply delete the wordpress_mu folder, replace it with the original unzipped contents, and start the installation over again?
Thanks for any help.
