You don't know how to do what at all? Post on a bulletin board? Looks like you just did.
This is a community of cat lovers where we meet and learn daily. Simply start reading the threads that are here, and if you feel you want to say something to the people who posted, just hit reply and type your message. Then hit submit.
This is a bulletin board, not a chat room, so there aren't always "instant answers." People check in when they can and respond to what interests them.
