Katrina Island?

It is my understanding, or impression that " two " people post under the heading of " katrina Island ", Gail or William, they being friends living in the same residence. How do readers know which one of these people is doing a particular post under " Katrina Island " ? I think it would be benificial for Gail and William to indicate in thier post, in some fashion clear to the readers, who is doing the post and making the comments. For myself, I would like to know which specific person the stated opinions from " Katrina Island " are coming from, that way you know who you are responding too when someone chooses to comment on one of thier post:-)
