It can be re-signing in if you don't choose "forever" when logging in, but reregistering would be sending me requests to approve registration. I haven't gotten any from you.

Try this, at the log in screen where it says "log in or register". Go down to where you put in your credentials and scroll down another inch to see where it says "remember me for" and there's a box saying SESSION. Touch the box to get a drop down menu that has choices. Choose FOREVER and you won't need to log in anymore.
