I guess the phrase is "Live and learn". When they, Blogger, say "Warning..." listen.
No, not me, I just hit the "OK ( or whatever)" link. Boom, the change is made. Me, no worries, I saved my stuff...sort of. Just redid my blog.
Just trying to change the look...I'm back where I started.
All of my blog entries were saved...good thing.
Warnings are there for a reason...no shit! Listen...I will from now on.
