Trying To learn This Site

Yesterday was my first time blogging on this site and I'm not quite familiar with it Just yet. I thought I was editing a blog yesterday by inserting a picture, however I was really creating a new Blog. The problem with that is now I have a blog with just a picture and no text!!! I didnt realize it until this morning and can't figure out how to edit that Blog. I will eventually figure out how to edit when I screw something up but it may take me a little longer than some of you females since I don't read directions.
