Greetings from America, Yvonne!
To address your point, yes, this online forum is intended to give IBHA members an informal space to discuss whatever topic. But a forum, much like e-mail, isn't "real time". I post something and then wait for someone to respond. That response might take an hour, a few days, or a week (or never).
So, some background on this topic.
FaceBook has been in the news several times this year for various (often disturbing) reasons.
I used FaceBook messenger almost exclusively to communicate with friends.
With all the concerns about online privacy and whether or not FaceBook is/isn't using my personal data for who knows what, I began to realize that I had become overly dependent on FaceBook as a method of communicating with people.
So I began shopping around for a tool to replace FaceBook messenger. After trying out a few different apps, I came across Telegram.
https://telegram.org
I messaged several friends and explained why I was leaving behind FaceBook messenger, and several people agreed with my logic and also installed Telegram. My friends and I use Telegram now for real-time communication.
You can use Telegram to one-on-one direct message people, or you can setup channels (rooms) where groups of people can participate in a group conversation. My friends and I have a general channel that consists of about a dozen of us, and we just have this ongoing conversation where we talk about whatever we want.
It occurred to me that I could start an IBHA channel on Telegram and invite big historians to join. We could use the channel for real time communications and share ideas, plan events, share big history related articles with each other, etc...
I think I'm going to go ahead and make the channel. We can try it out. Maybe no one uses it, or people try using it and lose interest. The worst case scenario is that no one uses it and I delete the channel.
I have Telegram installed both on my phone and on my computer. If you're interested in trying out an IBHA chat room, e-mail me your phone number so I can add you to my contacts and connect you to the channel.
