I use this great plugin with an "in memoriam" website that I made a few years ago for my grandmother. The plugin served as a place that people could "sign a guestbook" for those unable to attend her funeral. I keep the website up to date and maintained with the latest versions of WP, the plugins, themes, etc.
Lately I've been swamped with spam comments into the guestbook. They are all successfully flagged as spam, but I get e.mailed whenever one comes in and I have to clear them out a few times a day. I've switched from using a math quiz to using reCaptia, but the spam has only gotten worse. I'd like to continue to display the guestbook entries, but I'd like to remove the form to submit the entries, as there has not been a valid guestbook entry in over 2 years. Is this something one can do via the default.tpl template in the template/form directory? Any information you can provide would be quite helpful. Thanks!
