The Lion Guard has its section because the other sections of the forum were overflowing with TLG topics. Most of us on the site haven't seen much of the T&P show and can't really watch it, so there isn't much point in making a whole section of the board to discuss something people aren't discussing.
As Moka said then, if it gets more discussion, he'll make a section for it.
Also, I took care of your double posts for you.
