i don’t really know how to get badges. if anyone knows could he write?
Simple. You need to get/find a badge code and use it in TS Client.
Here’s the list of all known badges.
Please have in mind that some badges are unavailable, either because they’re not given anymore or their expiration date had passed.
Here’s a FAQ which gives a general overview of badges, the link to the updated list (thanks @SYOX) and how to redeem them.
