Hi, Grumps. There are various ways of keeping up.
If you click on My Settings, threads that you've posted on that have been posted on by others since you posted will be shown. Threads that you've posted on become subscriptions and if you want to delete a subscription, just scroll down further on the My Settings page and click on My Subscriptions in the left hand panel. This gives you a list of all the threads you have posted on with various options including deletion.
Clicking on Home at the top lists threads in the order of last thread created first.
Home is also where you will find the Members' Map. You'll find this near the top in the left hand panel. You can see where we all live (those of us who have flagged ourselves up) and you can flag yourself on the map too.
Clicking on Today's Posts at the top gives you a list of all the threads that have been posted to today. These are in the order of last posted to first and the ones highlighted are the ones you haven't read since someone posted to them.
You may already know all this, but I like to remind myself anyway.

Keep posting. You can see how many posts you've made by looking under your name in any post of yours.
