Well, if you aren't logged you'll see home pic like this pic 1
If you are user of IMCDB write your nick name (you chose one nick and your password) clicking in login
BUT if you aren't registered yet click there
and write your nickname, password (my advice is use the same nick and password that you got in the forum your mail and country. As you are already listed as a forum member you don't have to click in the space "Also register this nickname on the forum"
Later (I think remember) you will receive a mail and you will confirm clicking in a link.
Lately when you are logged your nick name will show in the upper side of your screen in black letters.
If after all you are in problems, write a private message to
antp. He will can solve this matter
