How to Create a Private or Public Channel on Telegram? The optimal dimension of the avatar on Telegram is 512px by 512px, and itโs recommended to use PNG format to deliver an unpixelated avatar. The creator of the channel becomes its administrator by default. If you need help managing your channel, you can add more administrators from your subscriber base. You can provide each admin with limited or full rights to manage the channel. For example, you can allow an administrator to publish and edit content while withholding the right to add new subscribers. In the next window, choose the type of your channel. If you want your channel to be public, you need to develop a link for it. In the screenshot below, itโs โ/catmarketing.โ If your selected link is unavailable, youโll need to suggest another option. According to media reports, the privacy watchdog was considering โblacklistingโ some online platforms that have repeatedly posted doxxing information, with sources saying most messages were shared on Telegram.
