The best way to add your audiogram is from the top of the forum web page, click on “Forum,” then “My Hearing Tests,” then sign into the main Hearing Tracker website (should be the same account user name and password you use for the forum, IIRC. You should end up on the following page: Add a Hearing Test (hearingtracker.com).
The official instructions on how to do it are here: How to add your hearing test / audiogram to Hearing Tracker - Forum Support - Hearing Aid Forum - Active Hearing Loss Community
When you do it this way, your audiogram will show up as part of your avatar. (the white circle with the black T or toadstool or ??? in it). Try clicking on my avatar or any similarly “iconed” avatar to see what I mean. It takes a little typing but it makes it easy for anyone to see what sort of hearing loss you’re dealing with in any sort of post you make.
