If you're wanting the post to reflect current date, you could copy and paste the entire post from in between these < >

Into a brand new post -- again using the  < > brackets so you're copying and pasting the code. Save this draft, make sure it saved. Then. . .

Delete the old post so you can use the same title on the new one.

Then you have a post with the same info and title, but new date that you can share.

This is how I would do it if the concern is that it's buried.

Sheryl Goldberg, 

Is it a new post and updated one?  Just follow Wanda Kubat-Nerdin - Wanda Can! recommendations  

Yes, otherwise it is outdated.

I just keep posting and flooding the airwaves with tons of blogs to always keep twitter, fb and others full of my stuff, never letting anyone forget that we exist.

Glad you asked because I don't have a clue and I'd like to do the same Sheryl Goldberg, . I'm glad Candice A. Donofrio came to our rescue.

When a question is asked here we all learn something new. Thanks Candice A. Donofrio for stepping up!

I'll be reading the other answers. Make it a new post?

It looks like you have resolved the issue.  AR Q&A is the best place to get help. 

This is a good question thank you. Tweaking an existing while in place doesn't quite work out too well while copy & paste does better. Taking what you thought to be good & reintroducing it makes sense & does much good
