The forum that you posted in your original post is the new and improved (but not 3.0 just yet) Equus Community forum. Equus Sims is different from that forum but they are sister sites. This site is primarily role playing with no money or credits just roleplaying. Equus Community has a credit system for horses and it also includes money and such. The second link you posted was the main site to Equus Community, where players make profiles for their horses and such!
