A tweak for 'About' at the top of my sidebar, a reminder for myself

I tried to edit the original message that was there with About section on the sidebar.
But I found no way to touch it with some kinda Edit pop up window.
After wasting 10 minutes, I decided to change the message directly at html.

So I went to Layout - edit html - (ctrl-f) and type in about to get to the area and them I wrote simply about me.
Now my sidebar's About section shows a declaration about myself and that's good enough for me.
