Thank you for the your interest in joining the Pune Parents TelegramGroup. Your application will be reviewed upon submission.

Why Telegram app instead of Whatsapp?  
In two days we crossed the limit of whatsapp group.
So no point in making 100 whatsapp groups.
Telegram has 10000 limit, so until we reach 10000, lets join and enjoy.

The link will POP up when you click Submit button. Do not close it. Click the telegram app link and join it. No one will message you any link or personally add you in the group. So do not close the  pop up after submission.
