Ray Farmer -
When we talked to the forum developers about the spell checker last year, they said they were hoping to upgrade to a more robust tool.  I will try to get a status update on this and see if we can get some standard NI words added to the core dictionary in the meantime.  
Unfortunately, I don't think regional settings will be feasible as long as they have the current tool in place.  But, I will let them know that this is a feature they should be considering when they replace it.
Thanks for the feedback!
