Hey @RafaelChampagne
No worries, we’ve all been there when trying to get the hang of Opera! To find Opera Mail, you'll need to open Opera and go to the "Menu" in the top-left corner. From there, select "Mail" (it might be under "Tools" depending on your version). Once you click it, Opera Mail should open, and you can set it up.
As for other useful tabs in Opera, the sidebar on the left has quick access to bookmarks, history, and extensions. If you don’t see what you're looking for, you can also customize your sidebar by right-clicking it and selecting "Customize."
Hope this helps you get started! Let me know if you need anything else.
Cheers,
Kera
