Midwife not a techie

So it was brought to my attention today that there were some strange comments to my blog.  I apologize to anyone who might have been offended.  I noticed this last year and I deleted alot of comments but I didn't change the settings so more comments were made.   I have now changed the settings to hopefully I have solved the issue.  As I said I am a midwife and am not a techie.  This does not mean that I want all the ads for someone to come and fix my website.  I like figuring things out for myself and if I want someone to take care of my website I would like to chose someone I know.
