Oh ok, it's not really that clear in the Wiki.
Maybe, whenever you have some spare time

, you might want to add in between brackets (reg. version only) next to items in the wiki who are only available in the registered version.
So if I understand correctly, there're 3 versions than, the Trial version, The unregistered version and the registered version.
Usually, all functions are available in a Trial version, hence my confusion.
Cheers
