How do I post in the forums?

To start a new thread in a forum you should visit its page and then click on the "Post new topic" link, on the upper left part of the screen. This will show you a posting window where you should write a good title in the "Topic subject:" field (instructions provided in the same page) and the body of your post in the "Topic body: " field.
If the planned thread will be on some of the tolerated off topic exceptions described in the Definition of ProZ.com's Scope you should click on the "This post is 'off-topic', ie. more play than work." box.

To answer to an already existing thread you should click on the “Reply / comment” button to create a new post or on he “Reply with quote” link inside a previous post to reply to this post in particular keeping it in a box inside your own reply.
