Do you change your logo for special days?

Not currently, but it's an idea I'd like to put forward to a few people, especially with Christmas around the corner :)

I use to always put up a Christmas theme on The Blog Herald...Halloween is too small a thing for a custom theme. Christmas themes though always solict positive responses.

I posted the images here if you missed them

Only for xmas.

At ineedhits we have done it for Christmas also.
Do you think it is worth time time and effort? Will you be doing it this Christmas?
