The link of the post you provided is different from the one I am/have created. That link is for guidelines for new forum members, while this is for forum related tools created by co-forum members for better use and access of the forum.
That is true but you can check the link and you can find some tools there that are useful even though it is not created by one of the forum member but still it is used by many people. One of it is the authenticator and there will be more of it I think. I hope that this thread will help everyone who isn't aware of the tools yet that it will be useful on their journey and would surely help them in contributing to the forum like the talkimg for it's purpose. You should have just post the list right away even If it's not complete yet and add the rest later.
