We are a newly formed housing society with around 400 houses and up to 800 members. We want to set up a group chat among us via any app which is cross platform (Windows, Android, iOS).
We have tried:
- WhatsApp but it has a limit of 100.
- Telegram increases the limit up to 200 and
- Skype 300.
But none of these are sufficient.
Is there any way to increase the limit of any of these applications for up to 1000 people to chat together?
