Hey there, Russ. It's a lower case 'w' since the name Pwcca is a Welsh name and not an acronym.

Having said that, I am entirely serious and not in the least bit joking. Having read a fair few articles on the subject of creationism, I know full well that it serves as an umbrella for multiple religions. Therefore, designating posting criteria to Christians and evolutionists alone (separate criteria no less, despite that the two do not oppose one another) omits all others from posting. I have read Islamic creationist sites, for example, and I see no reason why such a person might not want to post here. Up until the point at which they see the posting guidelines don't have any leeway for them or other religions.
