Hi! This is my first patch I've submitted here... I hope I'm doing everything right. Anyway, I was annoyed that, using the web-based spellchecker, if I used the same word "incorrectly" over and over it would show up in the suggestions list over and over. I suggested a solution, and patched SpellCheck.pm. The patch is at http://www.plover.net/~dglasser/livejournal_spellcheck.patch. Here is the behavior before and after.
If there's anything else I need to do for this, or if it has any unexpected problems, let me know!
