@tony_b , there are many ways to achieve this and as well as the index at the foot of every one of my posts/comments, as I mentioned in my earlier reply to @MattGatlin ,another good way is to setup email notifications as I’ve explained in T100 System > General > Links > Item #3. This way you receive an email in your inbox (example below), soon after any new monthly leaderboard post is published. @MortenCopenhagen also has an index to the leaderboards which I know some Local Guides bookmark and use. So there are many ways to find them.
ps: I’m now confident that the last of the leaderboards will be posted after midnight tonight (AEST)
