I believe Georgia is referring to the titles/badges that can be earned and worn here in the forum. They are a feature of the site that allows everyone to display a title of their choice next to the username, for all to see. This is what the badge looks like:
Many choose to earn and display titles that align with or represent their personal practice.
Some badges can be earned by interacting with the forum (liking posts, spending time in the space, sharing comments, etc). Other badges (like the “Blessed by Dragons” badge mentioned above) are given as a reward for completing a Witchy Challenge.
While challenges run for one week at a time, during Catch-Up Challenges all of the previous challenges as open (and their badges can be earned) again. The next Catch-Up is in just a few weeks! 
For more information about badges and how to set them, here is the original announcement with instructions: New! Badges and Titles in the Forum.
In short, they are a fun way to further personalize your account and display something that resonates with you and your practice 
I hoped that helped to clear things up a bit!
Blessed be
