As I thought, but best to get the word from the expert. The "Todays Post" is in fact a 24hr period. But near the bottom you will see the posts since your last visit. Since this is I check in often, I have not seen anything listed there. I would have to not log in over a 3-4 day time period. If anyone does that or will be doing that, please let me know if you are seeing listings in that lower section. Thanks!\
**UPDATE** please see if any of you see that bottom section on your account. It could be that it is missing from some accounts.
