To edit your name or bio, click the Menu icon and select “Manage Channel.” Telegram users themselves will be able to flag and report potentially false content. Your posting frequency depends on the topic of your channel. If you have a news channel, it’s OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. The optimal dimension of the avatar on Telegram is 512px by 512px, and it’s recommended to use PNG format to deliver an unpixelated avatar. 4How to customize a Telegram channel?
