Is there a way to communicate with a fellow contributor on the geogebra platform?
You can comment Activities posted by an Author, only if the Activity has been published after the release of the new site. Go to the Author's page, then select his Timeline page and select the thumbnail of the Activity you want to comment.
If it's possible to comment that Activity, your profile pic is displayed at the bottom of its thumbnail, next to a text box where you can enter your comments.
