Inviting observers to my new project

Hi All, could anyone point me in the direction of a way to invite other users to join my project group (‘Australia’s Untold Roadtoll - Recording Roadkill’ for anyone who wants to join!)
I do have it as an open setting group, but i would benefit from being able to specifically target some users who i think would be keen to participate also.

Just send them the project page and they can follow the “Join this project” link:


Or send them the join link directly:


There used to be a specific requirement to invite people to projects before their observations could be added and you had a page to manage those invitations ( But people got annoyed with continuos invitations to new projects, so they changed it so that anyone can add observations to projects unless the observer has opted out.
