Forgot Password or New Account?
If you have a username (normally your email address), but you do not remember your passord, you can reset it by clicking or tapping on "Forgot Password" (#1 to the left). You'll then be asked to submit your email address, and, as long as your email is in the Holy Trinity system, a new password will be sent to you.
If you are starting a new account, click or tap on "Don't have an account?" (# 2 to the left). You will then be asked to fill out a form, which will be submitted for approval for the systems administrator. In the meanwhile you should have some but limited access to Community.
