When we talk of cross-cultural exchange in AW, this is sort of what we have in mind: a Roman group hosting a Celtic celebration. Maybe you aren't aware that ghost stories are more or less universal, but take the time to check last year's Site-Wide Undead Trivia Contest, which started with this post to learn more about the different traditions - and also, to laugh at the antics of the competing teams ;-)
Does it sound strange? Well, take a look at Arachne's Web sponsored Haunted Homes Tour, created to celebrate Samhain.
It really is a webring of AW homes decorated with Halloween/ Ghost/Gothic themes. It is open to everyone, so you too can join, whether you be a Roman, a Celt, an Oriental or from whatever world in AW. There is no competition, just the pleasure in making great looking pages.
