online teamwork plugin

I want to make a plugin which could let peole to work online together.
could I make it？Or are there some plugins like that？

This sounds interesting, but too vague to give any advice.
I assume, that this is not viable with the LibreCAD plugin interface.

With LibreCAD 3 engine this could be possible as it was designed from the ground up to pass messages between renderers and push updates.
Still a lot of work though!

When creating something, you need to know all the market laws, although you create each product is focused on a certain circle of consumers. I would recommend that you first seek help here weareecs.co.uk, here you will be helped. In my time, I studied marketing, and I can say with confidence that before you create something, you need to know what consumers want, and to know their needs, you need to know who you are creating a product for. Having learned all this, you will enter the market with confidence and find loyal customers for yourself.
