To read the comments made about posts, click on the (tiny) word "comment", not on the picture of an envelope. The envelope lets you email the post to someone.
Another note: brand new posts always appear at the top of the screen. To see older posts made this month, scroll down. You can also look in the "archives" section at the lower left to see posts made in any particular month.
Be sure to scroll down and read the WELCOME post at the bottom of this page!
