Is there any way to directly add friends? Most of my game-playing friends aren't active forum posters, so I'm not going to be able to hover over them to send an invite, but I don't see another way to do it?

It's currently not possible to actually search for other people, but I think it's safe to assume that they'll add something like that in the future. For now, it's still necessary to find other people somewhere on gog.com and hover over their profile picture to add them.

Try to google "site:gog.com accountname". If they ever wrote a forum post, wrote a review, or created a GOGmix, they'll show up that way.

if someone has replied to them you can track them that way. use the search function in the forum and type their name.

Well, currently I can't manage any request here (Galaxy doesn't work), so don't send them to me for now.

Awesome! You did it without creating a new thread! You, sir, are a hero!

I will also post here for friends, we need to merge those threads, anyone who wants to add me can also do it, always looking for new faces.

definitely a bit of an oversight
