As it states in our rules, "This is not your tack room, and what you say can be read by hundreds or thousands of people. (Possibly including people you're writing about.) Please post responsibly -- just because you might be posting anonymously does not give you license to say things that you wouldn't want attributed to you."
Please do not contact the moderators and ask us to delete a thread because you don't like the direction the discussion has taken, or you've gotten in trouble with your trainer/barn owner/someone else over what you said. You are responsible for what you post, and as in real life, once you put it out there, you can't take it back. Keep that in mind when you post.
You can, however, delete your own posts. Instructions on how to do so are available in this thread in the FAQ forum.
