Yama-Kami: While I think the OP's silly to not want to be on Galaxy 2.0, as I myself have been using it without issue exclusively for some time now. Other platforms are now simply there as launchers/DRM in a nutshell. I would agree 100% it is a bit surprising there is still no way to access the forum via the platform. This is my 1st post in a very long time, due to this reason. It's truly the only complaint I have about it.  
 If the powers that be a GoG would please implement a way to access the forum via Galaxy 2.0, I am sure many more than just the OP and myself would be grateful. I'm sure it would be helpful for yourselves as well in getting more useful feedback as well. 
  Well, golly gee, if you've been using it without issue, then CLEARLY nobody else has any reason to criticize it and CLEARLY nobody else can possibly have any problems with it. They all must be doing something wrong because Galaxy 2.0 BETA is perfect down to the quantum level and it's absolutely 100% impossible that it doesn't run perfectly for everybody or that anybody might want functionality it doesn't provide.  
 My Galaxy client was force-"upgraded" to Galaxy 2.0 beta, and I immediately noticed two huge issues:  
 1. Tags don't work. When you right-click a game in your library and select to assign a tag, it shows there are no tags, and when you click the "Filter" button at the top of the screen and select "Tags", it shows only "No tags", despite the fact that your library on the gog.com website does show the tags you have assigned to your games. This is a huge issue for me, as I use tags to define categories (need to install, won't play, in-progress, pending, purchased for soundtrack, etc). With the old Galaxy client, I could filter by tags to list only the games I wanted to see. Since tags don't work in the Galaxy 2.0 client, I can no longer filter my library based on assigned tags, which means I can no longer select to view only the games matching a certain category (such as "In-progress"), making the library virtually unusable.  
 2. The Galaxy 2.0 client does not support keyboard access. You MUST use a mouse to browse your library. There simply is no response to keyboard input. Also, clicking on a game automatically opens the game page, so you can forget about doing something like selecting multiple games and setting identical tags for the group of games.  
 The Galaxy 2.0 client doesn't even keep the column headers on-screen when you view your library in list mode. Instead, when you scroll the list, it scrolls everything -- column headers and all -- and it scrolls the list up the entire window, overwriting the buttons at the top of the screen (owned games, filter, search, etc).  
 On top of that, when I launch GOG Galaxy 2.0, it stays at the "Launching GOG Galaxy" window for at least 3-4 minutes, with constant disk access, before the Galaxy client actually opens the window and becomes usable. Windows' Resource Monitor shows the disk access is in the "galaxy-2.0.db" file, averaging 1 to 2.5 MB/sec read access with 99% highest disk active time. That's on a 3-disk 16TB RAID5 array which routinely averages 120+ MB/sec when copying files. That suggests horribly unacceptable database performance.  
 So far, the only positive things I see about the Galaxy 2.0 client are 1) the library list mode can show additional columns (time played, last played, release year, etc), 2) the interface uses dark greys instead of light greys, making it much more comfortable on my eyes, and 3) the library list mode can display the games with smaller height, allowing it to display more games on the screen than the old Galaxy client. Those three things are the only benefits I see in the Galaxy 2.0 client over the old Galaxy client. The Steam client is so much more usable and user-friendly than the Galaxy 2.0 client in every way I can see.  
 In short, this forced Galaxy 2.0 "upgrade" feels very similar to a Windows 10 "upgrade" -- it's a broken, beta-level mess forced onto users without any notice or ability to decline it, and it cause headaches for many people. I will admit that it has great potential. Time will tell if that potential is realized.
