Dear all,
After getting almost all answers, the best suggestion would be to have a Telegram group. This was mainly pointed out for privacy reasons, in case would not like to share their phone number with anyone. If you could please be so kind to download the app, I can create the group straight away!
On a side note, I had a crazy week at work so I was really prevented from acting swifter on this. My apologies for not sending this message earlier. Hope to see you all there very soon!
