Several suggestion for improvements

[RH]

Hi Chris,
Here are some few suggestions :
1- Wordlist : it would be nice to mention the date of the last revision/update
2- Wordlist: an automatic message to inform about the new updates might be usefull (ex: we can register for language or type of list and be then automatically advised)
3- Stackz PC : it might be interesting to have the possibility to add pictures/images (instead of text only) via an hyperlink. Students might then study any domain (such as: recognize artistic paintings etc).
If suggestions are not valuable, please feel free to delete.
