It may be too early to be thinking about this, or perhaps there's not much interest in it, but the look and feel of the site is almost (but not quite) as important, albeit subconsciously, as the content itself, certainly to first-time visitors.
There are always elements of personal preference in deciding on look and feel, and I certainly have my own views about what I would and wouldn't like to see, but there may also be deeper issues to consider - for example would Catholics be offended if the logo for the site was an empty cross (as opposed to a crucifix)? What other sensitivities do we need to be aware of? What criteria should our design strive to meet?
