You can easily edit a message set at the top of your telegram group by clicking it once, without holding down. This will show the Edit menu (before the Delete entry) and you can go to edit it.
Remember that you can set up only one message at a time.
Telegram, a free cross-platform messaging application, has received millions of new users since the end of WhatsApp over the weekend.
Telegram gives you the ability to send messages and photos with a self-destruct timer, just like another popular app. Like Snapchat, you can still shoot these images or these texts before they disappear into the “secret chat”. Within a secret chat, all documents, videos, places and images you search for can be shared, lasting from two seconds to a week. The app is proud of its increased security, which attributes time-tested algorithms that combine security and delivery at high speed and reliability.
