To delete any message you can right-click on the message and click 'delete'. You can delete it only for you OR delete for the receiver OR all the participants in the group. 'Delete' option is also unique on Telegram as it does not leave any trace that you have texted to the team or your colleague.

==== Use of Hashtags ====
If you have a common term used in your project repeatedly that usually appears on your group or individual chats then better you prefix # tag for that word. This helps you to search all those #tag messages to appear in the search result.
For example, Education team has a major project named TIIE, whenever edu team plans or converse about this project they could use #tiie so that if anyone from the team needs an old conversation, they can simply go to the search bar as "#tiie" that displays all their conversation that has been tagged with this word.

==== Telegram users and admins ====
Generally there are three types of users in a Telegram.
* '''Owner :''' Owner is the the creator of group. Owner has supremacy in managing the group. Owner has the rights to do everything with the group. Owner can assign the members as administrators. Owner will have the ability to give a few or some or all authority to the administrators. Telegram considers the creator of the group as owner of the group by default.
* '''Admin:''' Administrator is the person assigned by an owner and is usually responsible to look after the group's activities. Administrators have the rights to add or remove users, post and manage messages, block members, edit group information etc subject to the permission given by the 'Owner'. Admin also has the provision to delete the message that user or admin or owner has sent to the group. Note that admin do not the have authority to create other admins for the group.
* '''Users :''' Telegram users are usually treated as participants/audience of the group. They are usually able to receive the messages, freely chat in the group, reply for a message, create and share posts, delete their own messages, create and participate in the poll, add members to the group etc subject to the permission given by the 'admin'. Note that a user can add other 'users' but not have the authority to remove them later on.
