does anyone know how to make cloud lists? I know its possible with varibles but I don't know how to do it with lists. I mean, I`ve seen it in certain projects before so I know that it works but I cant seem to actually do it.

search cloud list there is a tutorial by big-red-button and an engine by Lirex

But cloud lists can only be emulated; they don't exist. So for example you might join multiple values together to store in a cloud var and then expand back to a list when you read from the cloud.
