Welcome! Start here.
Welcome to OGS!
Contrary to first impressions, we are not a bunch of lunatics (except when we are).
We are all happy to offer our help (which might or might not end up being useful), but you might want to check here, here and here first.
Some less obvious places to find answers in important questions about Go can also be found here and here. In those two threads you can come across more advanced concepts, which may give you the initiative to explore additional information.
We advise you to play often and lots, but also keep up with the forums, you’ll meet our friendly team of moderators sooner or later. 
If you like what you see, stay and have fun! If you don’t like what you see, the shortest way to change is individual action.
Join us and meet the game that stands between the universe and human stupidity!
P.S. There is no consensus on whether this thread is serious or satire, you will most probably find out yourself sooner or later.
P.P.S. Also, we have an awesome Settings page, look!
