In the upper left corner of your gmail page, located under the word Google, click on the small arrow next to the word Gmail. Select Contacts from the drop down menu. This will take you to your contacts page where you can edit, add, or delete contacts.

Hi,
You can change both the user name and password that are in the login screen. They make it confusing, you have to 'add' or 'delete' a person, but this doesn't actually add or delete anything but the cookie on your computer giving the expected list of users.

Hi,
No issue just visit this link and follow instruction. Your email account message delete.

To delete a contact:

1. Select the contact in the Contacts list.
2. Click More, then click Delete contact.
3. If you change your mind or mistakenly delete a contact, you'll be able to recover deleted contacts for 30 days. But 30 days after you delete a contact, it will be removed permanently.
   If you use Google+, deleting a contact will also remove them from your Google+ circles.

open your gmail account than click on "contact" on the left side this will bring you your contact list. choose the group where is situated the contact you want to move. than select that contact than click "groups" and choose the new group you want to move the contact in from "add to".
Now this contact is linked to two group cathegories.
Just do same and select "groups" than "delete from" instead of "add to"

Hope it helped !!

try to login to gmail and check if address book contains the contacts which you are checking...
If they appear, then check the settings of your gtalk

how can i see my delete chat list
