Iap. I agree with jieduck. Not all of the members here celebrate same holidays.
Ie, i don't celebrate xmas.
Well, i think a topic to celebrate holiday is enough.
You can post your wishes etc in that topic.
We don't need to change the whole forum.
Beside that, members here have set their own ftalk style. So, if we design a new style for ftalk, it will only affect the guest.
Hope that you get my point.

Anyway, that was a nice idea.
And i have suggested that in Contests and Events section several weeks ago.
A ftalk style design contest.
Why don't we give members here a chance to design the ftalk's style.
