The Newbie Helpers have now changed title/role to 'General Helpers', and you should feel free to contact them if you have questions or need help with CS (even if you're not a newbie!)
The General Helpers are regular users who have volunteered to help out, and they will do their best to answer questions you have about the site or forum.
We are not looking for new volunteers at this time, but there is nothing preventing you from unofficially helping users around the site as they do.
