Yeah I have the same problem.
I find it reverts to German because it doesn't remember you. Once I log in, or post a reply (which requires you to log in). However when logging in, without posting a reply, it takes you back to the main forum, and once you click on the Camp America link it takes you to the participant forum.
I find the only way to get to this forum is from the link on the http://www.campamerica.com.au
Its unfortunate as we want all new applicants, or people considering applying posting here. The applicant forum is really busy wiht lots of new stuff daily but non applicants can't see it unfortunately.
