Yes, the NEW signature would be in the signature box following your post on ALL posts. 

However, if you typed the address within your POST, you will have to go back and manually change all of them. Been there, done that and it's not a quick process!

   Two separate updates; sounds like you have done both of them.

 1.  Edit Profile Page

         There are some things that cannot be edited.  If you have problems with your Service Area, or any other issues,  contact  Support@ActiveRain.com

2.   Your blog signature which appears at the bottom of EACH and EVERY post that you write (or have written).   

        How to edit the blog signature was answered on your previous question.

 ***  Suggest:  Never type your personal contact information, URL, company, address, website, etc. in the  main body  of your blog post.   As Debe Maxwell, CRS said in her answer, you would have to go back and manually edit every single post.

The signature is a permanent one you create and replaces all previous and appears on all past-present-future posts. Lyn Sims shared this too.

I don't think you understand the format.

Think of your signature as the automatic bottom line of every post.

Sheila,

The signature stays permanent, and if you change it, it automatically changes everything, as Debe Maxwell, CRS and Lyn Sims stated and others also.  A

Good luck and have a great day.

Fred Griffin always has the right answer with a complete explanation....

Debe Maxwell, CRS has this one covered.  Once the change is made it covers ALL posts. 

The ActiveRain membership is quite helpful.

The techies here in the Rain will know!

I honestly don't know.

All of us, Shaila, time to time changing our signature and update information and links.

Unless you added another signature in your blog, the new one should be the one that shows up.

Your new signature should be on all your old posts now.

Debe has answered.

Your new signature will replace all of the old ones in all of your blogs.

Well done

Once you change your signature line it will be univeral for all of your old posts.

Your signature is in settings. 

Anything within the post remains same, Sheila Moylan Realtor. 

Glad to hear you have it worked out

When you change the automatic signature, it should appear on all of your posts where you used the automatic signature.
