that makes sense, except I do not have an island 80 min only goes to 54
What you have to keep in mind is that.
Canned portal islands
Post islands
Gallery islands
Each have a limit of say ten islands each.
So they are reserved even if you don't use all of them. For the most part.
Then here comes custom islands. Which can be unlimited.
Then you have custom islands that are deleted.
So the number keeps increasing.
best way I know to explain it.
So you could have a portal box 80 file even though you only count 50 something islands.
