What is the difference between space and subspace?

[Thiagarajan]

We were creating multiple spaces. We tried creating subspace but we didn't find any difference.

[Davin Studer]

If you are using one of the sub-space add on it is just creating regular spaces and using some internal add-n logic to create a tree structure for the spaces, but they are just normal spaces.

[Nic Brough -Adaptavist-]

That's because Confluence doesn't have sub-spaces.

I think you need to explain how you think you are creating "sub spaces"?
