BlueTie's Instant Messaging application allows users to block individuals that they do not wish to receive messages from. Blocking a user will also prevent the user from being able to view your online status. You will appear as offline to all users in your block list.
To Block a User:
1) From the application click on the IM icon.
2) Next, click on the Options button located under the text box.
3) Select the Add button below the block list and type in the username you wish to block.
4) Click OK and the user will appear in the Block list.
5) When finished, click SAVE.
