I had the Q&A plugin installed on my site and there were 17,000+ questions posted to it, all spam, except for two questions. I could not uninstall the plugin or delete. I caused the hosting company to have to migrate the site to another server because it overloaded their sipayte and caused it to shut down. I would like to use this plugin but I could not get it to work properly. Please advise. Peter Gibbs at peterg@theggoc.com is my Webmaster. Is it possible to cc him on this topic as he handles all of our website issues. Thank you.
