I have 'phpSpell v1.06p' (Spell Checker for forums) installed and it is working nicely in Icy Phoenix. I can post the install and changes I did to make it work if you want?
The only issue I have left to solve is how to add this option/button to quick reply option. I cannot seem to find the code where this lives to add the small bit of code to get it too work. Can someone tell me which file to edit so I can add a button to the bar with submit/preview for quick reply?
Oh BTW phpSpell is actually a somewhat old spellchecker but what is nice is that it is self contained on your server the dictionary db is stored on your server. Not like some of the newer mods or programs which go out to a off site server and does the checking.
