SmugMug features question

[tomd]

I am looking for info about features available on the different SmugMug level accounts.

I don't understand their grid? For example is watermarking available on all levels?

I see empty grid boxes without any check marks etc.

reply to self:

It must be a firefox thing.
below is a screen shot from the same page in Explorer.
