I can't figure out how to do this, help?

Slow down, you don't have to make so many new threads.

Go to your game. Click Post a New Topic. Write something and give your thread a title. You can preview it or post it. If you change your mind about it, you can edit it.

Also, people will tend to write back to the posts you make asking for help. It might be easier for you to get the help if you ask new questions in the same thread. Otherwise, you might miss an answer you need because you forgot to go back to your old threads.

Also you may want to consider looking for a game to join first, before taking on the task of running one yourself. When you are in a game as a player, you can get more of a feel on how things work on that side. Then when you move on as a GM, sometimes it can be a bit easier to understand.

Just a quick check: are you the GM of the game?  Only GMs can make new threads.
