Replacement variables: non-case sensitive?

[Kathy]

Hi guys,

I have a list of a few words that on my forum aren't appropriate. Sometimes though we get a drive-by posting...from someone that is just trying to flame the community and offend.

And so, to take away the offensiveness, I've added these 3 words to the replacements with a nonsense word to replace it.

the problem I'm having is sometimes one of the words slips by with a different formation of the word and mainly with an upper or lower case letter difference somewhere.

this could be fixed if these replacement variables were non-case descriptive.

Any way to do that? thanks for any ideas!
