I found your email address via this thread (DOES NOT WORK):
I am having trouble with your plugin remembering certain spellings. When it comes across a word it believes incorrect, such as "timeline", I press the 'Add to Dict.' button. It moves on without error, after pressing the button. However, when I run the spell check again - it prompts the same word again for correction.
Any idea what's causing it not to work correctly? Thank you!
PS: I tweeted your plugin, see it here:
