First off, I have the same question as Attie, you need to be logged in to post.
Then I thought a bit ans maybe you intermittently cannot log in. This brings me to another point. There is a checkbox where you log in that saya remember me. If you check the box, you should automatically log in every time you visit the site.
Some causes of inability to log in are. Caps lock on. If you leave the site and come back quickly, maybe the server has not gotten you all the way out.
Other than that, I am sure that a mod will be along shortly.
One difference between a cook and a chef is that the cook mows the lawn, while the bread is rising.
