Perhaps you received it. An email advising you that as of March 8th LinkedIn is changing the URL of the page that all your Posts appear on.
Yes, the most recent three (and the rest, if you click further) will still appear on your Profile page.
But your new Post author page will also show all of them in one place.
If you publish LinkedIn Posts (and I hope you do!) please add this link to your email signature so readers of your email can see your most intelligent thought leadership in LinkedIn.
Yours is the same, just with a different name tacked on the end.
Be a thought leader. Nurture the personal learning network we all have with each other, especially through LinkedIn.
