+
+VAILD_EMAIL is the regex used to valid a user given email.
+
+A break down of the regex is listed below.
+
+/ -----------> Start of the regex
+\A ----------> match start of a string
+[\w+\-.]+ ---> at least one owrd character, plus, hyphen, or 
+			   dot
+@ -----------> literal ampersand
+[a-z\d\-.]+ -> at least one letter, digit, hyphen, or dot
+(?:\.[a-z]+) > ensures that the error of example@foo..com
+							 does not occur
+\z ----------> match end of a string
+/ -----------> end of the regex
+i -----------> case sensative
+
+=end

+
+VALID_USER_NAME checks to make sure a user's user_name
+is in the proper format.

+
+The following lines put a user accout through a series of
+validations in order to make sure all of their information
+is in the proper format.
+
+validates :symbol_to_be_valided
+
+presence: determines whether or not a symbol is filled or not
+length: ensures there is a length limit on the symbol
+format: checks the format of given information to ensure 
+        validity
+
+=end
+
+	validates :name, presence: true, length: { maximum: 50 }
+	validates :email, presence: true, format: {with: 
+                                       VALID_EMAIL_REG},
+                      uniqueness: { case_sensitive: false }
+  validates :user_name, presence: true, length:{maximum: 50},
+                        format: {with: VALID_USER_NAME_REG },

+=begin
+
+Instead of adding password and password_confirmation
+attributes, requiring the presence of a password, 
+requirin that pw and pw_com match, and add an authenticate
+method to compare an encrypted password to the
+password_digest to authenticate users, I can just add
+has_secure_password which does all of this for me
+
+=end
+
+	has_secure_password
+
+	validates :password, length: { minimum: 6 }
+
+=begin
+
+in order to ensure that someone did not accidently submit
+two accounts rapidly (which would throw off the validates 
+for user_name and email) I added an index to the Users 
+email and user_name in the database to ensure uniqueness
+This also gives and index to the user_name and email
+so finding a unique user SHOULD be easier
