You can click on contact us on the bottom of the page and ask Veronika to delete your message. I think it might be easier for her when you cut and past the url of the message that needs deleting. We have been having this problem for several days now, I wonder if it's a site problem? (Usually I only bother her if it's really important.)
No, I wish there were. You can edit your answers, but once you ask that question, you're stuck! And if you're using a touchy touchpad, sometimes those duplications happen. We know you're not dorky, Migs, hee hee hee. But it is annoying, isn't it! Hugs, Marji
