We have a request thread here on the forums for it, and the curators of the site can add games as needed. How to request games to be added to database? - #62 by BMO is the thread. We’re working on a ruleset for how and when to add games right now.
In theory this should be your avatar from the main site, although I’m not sure what happened on this one 
If you go back to www.grouvee.com, and click the Forums link on the top of the page, see if that updates it to your avatar from the main site. If not, I’ll have to go back and look at the Discourse API and see what’s changed.
Welcome!
