I don't use the ignore button...use to. But I found that inevitably, someone else will always quote that person you had on ignore anyways.
I often write out a post and change it before i click submit because I don't like the way it sounds.
Usually I end up asking myself (and maybe it might work for others here?) "Would I like it if someone answered me like that?"
Sometimes my answer is "no" so I end up changing it to a more "polite" reply
You appear to be a gentleman, Dom.
