you type @and then start typing the person's name (no spaces after the @sign).

Note: sometimes you can't tag someone if they aren't subscribed to you unless they happened to comment on the post.

Now Doyle Lee Austin Davison Iv you know how to tag Debbie Gartner and just ask her any questions you need answered.  She truly knows all the ins and outs of AR.

The experts have spoken.

You just hit the @ Sign and start typing the first few letters of their name.  If they are someone you are following or if they have commented on your post, you will get a drop down box with from which you can select their name.  Hope that makes sense!

Good answers here.

Also, I have noticed that the tag doesn't appear, because it does not like that you are on the next line.  So you have to backspace to the paragraph, do the @sign, and then space it in a new paragraph.  

So glad Doyle Lee Austin Davison Iv .  Thx Susan Haughton, you're so sweet.

@sign

Tag, you're it

Pretty good suggestions here, Doyle.

Use the @ symbol.

Debbie Gartner nailed this one!

They have to be in the comment thread or someone you follow. Use the @ symbol followed by their name and it should pop up.

As you know, no more tagging for points, but you still can tag.

I will miss tagging.
