If you change the course of a thread, then change the title to make it easier for others. Or start a new thread. Note that off-topic posts are sometimes deleted. Personal messages should be communicated by e-mail, not in a post. Send it to a specific person, not to the board.
Most posts have the poster's email address.
Flame wars or personal attacks on other board users are not welcome and will be deleted. You can post after you're more familiar with the Board. You'll see boxes for your name, your email address, and your message. Simply type in the information. A name is required.
