Thanks for the reply. Yeah I think moving the fonts else where is your only option with the automatic updates really, perhaps include the default set you supply in the plugin's folder, but have another location that you can check for the existence of extra/alternative fonts (pretty easy with scandir in php5, and there's some suggestions for php4 on the scandir page).
Sorry I didn't realise the overwriting of the word list was related to the automatic update problems. I always assumed that you changed the words on update as a security measure, so my thought was to make this behaviour optional. The problem of automatic updates overwriting the word list could be overcome by simply migrating the words to an option like the rest of the settings.
Yeah I haven't really checked out all the different branches yet, thanks for the suggestion.
Let me know if you'd like any help with the checking for fonts thing, I'd be willing to throw something together when I get the chance ;-)
Thanks again for all your hard work
