Is there a way to edit my own Blogs from time to time?
I sometimes see a need to update information I earlier posted in a Blog of my own.
Recently I attempted to post a new Blog but my post contained too many characters and I had to separate the information into two Blogs. I would now like to add a link from Part I to Part II and vicey-versie.

This would help to save some confusion to a reader and make the two Blogs one as I had intended in the first place.
Later I may want to add related photos also.
Am I missing this "edit" mechanism somewhere?
