Who wrote a post
Every post records the person who created it, shown with their photo on the post card. Clicking the name opens their profile. This is for your team only — it is never published with the post.
Seeing only your own
On a team, the calendar has an Only my posts filter.
Tracking links
A link in a post is tagged automatically so visits from it can be identified in your website analytics. The tag records which network the visit came from and, where a brokerage has more than one office, which office's listing earned it — so two Google listings can be told apart. A link you have already tagged yourself is left exactly as you wrote it.
