If you go onto a match, say today I had an email with a new match, and I clicked on it, and was taken to a page, at the top of which was the match details for me and the new match, below which was a summary of details:- estimated relationship, % DNA shared and cM's, number of shared segments and longest segment.
Then below that is a list of shared matches, giving details of how much each of you share with each additional match ( good info you don't get from Ancestry). At the far left of some boxes there is an icon, which has purple lines on it, and I wonder if this is what Essnell is talking about. However this is an icon indicating a triangulated segment, and if you hover over it, it says that. If you click on the wee arrowhead (part if the icon), you go thru' to a page with more details - basically a chromosome browser showing each chromosome and where you 3 match with each other, and indicating that there is a triangulated segment, and what the details are of the segment.
I wonder if this is what is being talked about?? - definitely purple/mauve lines!
What do you think??

PS should have also said that on the summary page, below the joint matches you get a basic chromosome browser indicating the segments shared with the primary match, and a comparison of ethnicity between you and the primary match. A very good summary page for each match, in my opinion.
