ConjurerDragon: When I’m in the forum and use the "search" button to search for some topic, e.g. last time searching for
"browsing games not owned"

I get a list of hits for those words with links that I can click to go to that thread.

However when I click one of those links I always get an error page with a huge blue globe.

The problem is that the link that is tried to be opened looks like this:
https://www.gog.com/forum/general/owned_games_not_marked_owned/?search=browsing%20games%20not%20owned

and when I simply delete the last part of that
"/?search=browsing%20games%20not%20owned"

then the link actually correctly leads me to the thread where my searched words were found.

Goodaltgamer: When ever I want to find something, I just use my normal search-engine (yahoo/google/whatever) with the following search:

site:gog.com browsing games not owned

The site:(here gog) will restrict the search to gog only.

Maybe that will work better for you?

And on busy days you can get easily the bear anyway. ;)
