[Share] Excel Mini-Chat System

Hey Guys,
I've been searching for a solution to make a "internal-chat like" using excel for sometime but i didn't find anything conclusive so I made one and i wanted to share it with the community, maybe someone somewhere sometime will search the thread and use it as well.

Why I did this chat system when it can be easily replaced by Skype, Discord, Slack, etc etc ?
For the conditions i had to make it in order to not use any Internet access type data's and every "sent message" to be stored somewhere

What does it do?
- Send and messages though lan using a common network local area network (can be modified for queries )
- Check / Uncheck if you want the data to be auto-updated every 5- 7 seconds (maybe mismatched the numbers)
- Double enter from the keyboard to send message
- Manual refresh etc
- Auto - Scroll bars?
- Everyday a new txt file is auto-made


What I want to add in the future?
- Windows notifications :
# Calculate how many messages people had sent until your new update?
# When someone joins the chat
- Message when someone enters/leaves the chat room

Have no idea how to do:
- Private room
- See how many people are present in real time
- send cat gifs?


Every idea to be added to it is welcomed, every critique is blessed. I want everyday to improve myself.

Thanks for sharing.

Although I am unable to share the file as it is not my property but my boss has developed the chat window where the admin and employee has different boot straps. I like it so much.
