Pardon my ignorance if this suggestion hasn't already been posted. But would it be a good idea to have some sort of firefox addon that allows you to, if you see a character on a website you want to learn, highlight it and add it to your skritter queue. I've been sending some emails to a Chinese friend to get some practice and they often come back with some good words and characters I can use, but I have to add them manually. I know it is not too much of a task but I think a firefox addon really would improve learning when you're looking through Chinese texts online.
Thank you
