I didn't want to give up the Excel icons, but I also wanted to change my icons... so, I just made all new Excel icons.
Of course, once I got them all made, LJ had to be crappy on me, so uploading them was a bit of a bitch, but I did it.
Although, there is a cynical part of me that thinks LJ added this feature because of Greatest Journal. Who... they kinda slam Here. Yes, GJ does have advertising, but it's not really obnoxious.
But, right now I'm just enjoying the sparklie goodness of 20 icons!
