steam had a huge ****** a few hours ago, people could see random users name and the last 4 digets of their card, be careful out there i don't know if it's fixed yet.
i know for games you can get the cards and make backgrounds and stuff like that but i have all and cant seem to make a badge, maybe ill just check with steam about it.
I am steam level 50, so perhaps I can help explain. For playing a game, you get ~ half of the card set for free, the other half you have to trade for or buy. When you have a complete set, you go to your badges to craft the badge. it will be a level 1 badge. you can complete normal sets 5 times to get a level 5 badge, or a foil set once to get a foil badge
i only have lvl 17, i've made some before but i can't seem to make the winter sale one, i'm just going to wait a while and try again, if it doesnt work i'll try contracting steam.
but do you know when the lvl's stop getting you anything. i think in the summer sale you needed lvl 10 to vote on the next discount, is there anything you get at higher lvlvs other then more friend slots?
i like having the badges for games i like, i have the FTL one because i really like that game, no shame in showing people what games you like on steam.
