Can't I be a Yahoo! group owner AND moderator at the same time?

first of all if you remove your self as the owner of your own group and something happen..you no longer can fix anything in your group. To be a moderator and for you to do that..if you have another e-mail..log on to yahoo and join your group with that e-mail. Now log out and rejoin it with the name you are useing as the owner. Now when your in there look for your other e-mail and then go to edit member and make your self a Moderator that way..I have done this in a few groups on my own and I even made myself a owner with another e-mail i use and the reason is for that if you lose your pword for one e-mail and yahoo id you have your other e-mail as back up..you have to be very careful how you set your self up as if you don't..you will never get back into your group. Now as far as why your approving your own posting go to the Management and then click on Messages next and click in there and then click on Posting and Archives and then go in edit and see how you have it setup..that would be why you have to approve of your self..if you only want to do that for members you need to change this
