Check this list to see what medals you want to apply for. The process isn't automatic; you choose which medals you want, and then a super moderator will cross-check to see if you meet the requirements for it. Et voilà , the medal becomes yours.
You sure do and congrats again!! Those will be delivered by the person running the events, they will come soon!
That medal is if you are online for 50 days, not your account age, you got a bit more to go before you can get that one!
Ok, so I read some of the medal requirements and I qualify for: Starter Poster Birthday Bash Creative Passion
I have given you Starter Poster and Creative Passion, afraid it is past the time which you can request Birthday Bash since your Birthday was about a month ago, sorry!
