Problem with this way of doing it

I think there is a problem with this way of doing it because we are all logging on as the owner/creator of the blog so we cant really respond to the things each other post in the same thread. You have to make a new thread or edit the previous one which im afraid we are going to screw up each other's posts. I dont know if there are some other ones we can check out this one just seems to be difficult. I dont know maybe we can do one where we dont need a password but just dont let anyone know what the website is other than the people in the lifegroup. I dont know whatever works...i used to use one called like blurty or somethin and that was a lot simpler
