Default Broadcasting using Conversations Feature

Hi everyone...

How can I instantly message all members and if possible maybe conditionally like for instance active, online or New.

Or

Possibly when creating a new conversation, use a wildcard character in the recipient field, for example * that represents all.

Please bear in mind that I am talking about the free version. There is however a broadcasting module, but in the paid features.

Thank you in advance for any reply.

Regards

Chris
