Hello Harro de Jong ,

The screen shot you have provided shows simply the bookmarks option- is this the popup you are referring to?

Maybe Lennert Fransen can help further.

yes, that's the popup I'm referring to. But it's not just the bookmarks option, it starts a tour of the site. It opens whenever I log into the Community site after I've been away for a while.

The problem is there's no way to close the popup other than by clicking "later"- which guarantees it'll show up again at some point.

The popup overlaps the 'New' button.

Hi Harro, 
I understand what you want, being able to also have a button to click that ensures the 'Welcome tour' through the SDL Community doesn't come back, like the 'Later' button does. I'll look into this and see whether we can add functionality like this.

Moving the thread to the Community Help group now

Hi Harro,

At the moment it's not possible for us to add this functionality our self.
I've opened an idea/ER with the platform vendor.
Hopefully they'll take action soon and add the dismiss option!
