I've been using Ryan Duff's Contact Form plugin for a while now without any problems. It is the only way of getting in touch with me through my website short of posting a comment on one of my posts.
However, for the past week or so I've been bombarded by spam sent through the contact form. Most of the emails have an attachment which, of course, I have no intention of running/loading/downloading..
Are there are any varitions to the contact form plugin that will add some level of user-checking, captchas or anything of the sort??
