Ah, no problem!!
A network is just a group of people who all like the same thing (in this case, Tolkien and his works). They usually have tags to track, in case anyone wants to share updates or posts that they like and a secret blog that all the members can be a part of as the network chat area.
It doesn’t really do nything, but it is a place for people to connect more, and it’s great for seeing more people who have similar interests as you or are in your fandom
It’s fabulous, and I really hope more people join, because I want to have to many more Tolkien blogs to talk to, so go HERE to find out how to join Thorinz’ and my network!!
