I don't know what the big deal is.  If you're even in doubt just tag it -  I tagged this image:

http://www.renderosity.com/mod/gallery/index.php?image_id=1378740

because I was afraid the aeorola was showing through the dress though it might just be the lighting.    So a few people who have nudity blocked won't see it.  It's my conviction that there are very few of those, even the ones ranting about nudity MUST have it allowed in order to be so knowledgeable as to what they're ranting about :)

The funny thing is I even got an IM from someone who commented on the tag and telling me I could very well have just left it without an adivsory since the nudity is so mild but I think I'll just tag everything I post from now on - I'd rather have people who are not opposed to viewing nudity viewing my gallery any day :)
