How Communication Works on Telegram

Telegram offers three different types of end-to-end communication styles in its channel feature:

• Private Chats (this can include many more than just 2 individuals)
• Groups - usually limited to 2,000 members - operate like chat rooms, anyone can speak freely.
• Super Groups - limited to 10,000 members - operate much more like a TV channel; limited to only administration who can make posts

Both groups have administration rights with specific sets of privileges to help you run your community. Choose who among your trusted admins will be able to add new users, manage messages, block members, edit group info, and add new admins.

All three are usually invite only.  Most invitations expire between 24 hours and 15 minutes.

Yes, Sticker Emojis Are Important

Notice, Telegram 7.0 improves "sticker" use for channel admins. Though stickers may on the surface seem superficial, they can play a great role in online communication.

FOR FORUM VISITORS, THE SYMBOLIC MEANINGS OF EMOJI SERVE SEVERAL IMPORTANT FUNCTIONS:

• for greetings and self-introduction (if person just entered a forum)
• ask questions and get replies
• underline a group affiliation (The Islamic State, Al-Qaeda, etc)
• support for thoughts/feelings 
• to define nationality and geographical location.
