Cloud dB limit and app inventor account after not using

[TIMAI2]

@Hisham_Hafis

So can I use cloud dB itself

You can, but:

1. You may run out of space (the MIT cloudDB files max out at 5mb)
2. Your data may be routinely wiped, without warning, by the server to recover space for other users
3. Connectivity may be slow or difficult at times of high usage

How do you create chat room with CloudDB?

I will like to create a chat room with CloudDB but will it be compulsory for those in the chat room to have the app ??
