A shardbuddie is where you both follow each other, and then mention the other person somewhere. (usually in your signature, but I have so many that they are now on my profile in my About Me )
In my signature, I have the people who I've known for months, and really love (platonically)Which why they are my "shardfam"
Then, with Part of The Narative, I know her IRL, so we do all kinds of goodfy stuff together on here!
Ta-Da!!
