Welcome to Tale of Horses! Here are a few pointers to get started with.
1. Read the rules. They are located in the Game Related Chat board. This step is very important, as you need to know what the rules are on this particular forum.
2. Make a horse. This is also quite important, as without a horse you will not be able to roleplay. Go to the Create a Horse board, then copy and paste the form into a new topic. Fill out the form and post it, and a mod or an admin will approve it for you.
3. Join a herd. This step is optional--you can also make a lone mare or stallion. If you do want to join a herd, go to the Herd Creations and Joinings board and pick one. You can also make your own herd!
4. Get RPing! This is the most fun step. Go to your herd's roleplay page, and make a post!
