Wish List Plugin

Hi,
I just recently downloaded your wish list plug in and while I like the ease and simplicity I do have a few issues that I'm hoping you can help me resolve. 1.) The text add to Favorites seems to be in a different language, and I do not see anywhere in the settings an option to change it. 2.) I don't like the option of the customer to have to be logged in in order to like the item. 3.) The number of likes is not calculating, its seems to be stuck on zero no matter what I do. Is there a way to change these issues, I really like everything else about the plug in and would hate to have to deactivate it. Thanks.
