It has absolutely nothing to do with being condescending. That would be, what I did towards you in the multibox thread for good measurement. But I have seen this thread on a couple forums and whenever people make requests for someone else to actually write an addon, that means they can't do it themselves. If they could, they would at least post an attempt, explain where they failed and ask for help.
I usually go way out of my way to help people who request help properly, but I will not spend a couple hours of my limited spare times on developing a vanilla addon (really annoying to do) unless I see a point to it. I even pointed him to in the right direction of an addon that would partially solve his problem.
And while I don't necessarily like Crowlock, I can at least acknowledge his will to try. Not to mention I don't see how he was being condescending.
