Hello.
I am very happy to participate into as many projects as I can, however in these days of COVID-19, I would rather be able to make sure
to get my cycles working on stuff with a sense of priority.

I have been playing a while with the projects preferences but I cannot seem to get the ones I want to participate into (namely, Rosetta@home which I have an account with since 2008 anyway).

Looking at the compute preferences etc. I can see the scores etc but it doesn't seem to have enabled projects, but then I realized there is a "Opt-out' column.
How can I opt-out from some projects so that, for the moment, I can cherry pick which projects to donate some Watts to?

Many thanks,

If you go to your "Science Projects" page:
https://scienceunited.org/su_user_projects.php
... and click on a project, you'll see an "exclude" button.
