I have some suggestions concerning the wordbank and word bank flash cards.
a) it would be good, if one could arrange the words alphabetically - so it would be easier to delete duplicated entries and words that you already know.
b) in the word bank flash card section I would appreciate a possibility to put the cards on - lets say - three different decks (good, bad and "más o menos"). Still better it would be if the system could memorize where I put the card today, so that I could repeat e.g. only the bad ones after the next login
c) the printer friendly version of the word bank ha still a bug. It doesn't show correctly the special characters, at least not at my Mac.
