Tips are active for 28 days. The list is posted every week. @ColonialCousin runs the program every Sunday evening, at around 10pm, so the list contains all the active tips as at that time. And yes, they are the tips posted in these threads. It is chronologically ordered, so the most recent tip is at the top and those which are about to expire at at the end. Feel free to enter a tip. Just make sure you have the right header. You can see the format of the header in CC's footer in his posts and there are numerous tips already in this thread so you can also see the format there. And if you want to see the rules, there's a link in CC's 6th post, just below the library links. Hope that helps
