For anyone having questions on signing in, posting, etc. here is the spot to ask your questions. This forum is easy to navigate once you get used to it. Most health forums do not have separate categories like this one, so that can be somewhat confusing when you first get on it. We have these different areas because this forum is dedicated to stem cell discussion for all diseases. Remember, when signing in that your name and password must be logged in just as you first signed up. This area is case sensitive and seems to cause the most problems for the first time user. You cannot post if you are not logged in. You can read, but not reply. I hope this helps. Also, if posting a lengthy reply, you only have 15 minutes to compose your message or you will be automatically logged out.
