This suggestion was made many times before but i has now come to fruition. You can now edit your posts in this section without limit. This means your cj threads can be kept up to date without needing to make a new one every time something is added.
However, this came with a down side that will not please everyone. I closed all current threads. Reason is simple: people would abuse this system and we need a benchmark for stuff that might have been allowed before the rules of teaching were added. So, this means that everyone will need to, in time create one new CJ thread, your last. That you will be able to edit indefinitely.
This is a privilege that many have requested and I hope that a few won't be the cause of returning it all to how it was. So please, don't forget to abide by the rules. Obviously, if something isn't in your current cj thread by now, it can't be added in this new one without proof of training in it. Thus why the other threads were closed. So a benchmark of your original cjs could be established.
In time, the old ones will be archived. But only in time, so you have time to create your new ones.
