I "borrowed" the pictures from Chris Ryall's blog, and if you want to read a little more about what he has to say about the Smile Time-covers, click here.
Below are some of the other covers for Smile Time.
The adult stuff, that you were warned about before entering the site, is for example vids that show sexual scenes (for example Spike&Buffy sex scenes), dirty manips and the occasional crude joke.
Spoilers for comics, movies, etc etc, will be marked/told, so you don't need to be afraid of being suddenly spoiled (so don't skim the posts in case you're afraid of spoilers).
[My own deeper articles and analyzes about characters, episodes, etcetc, will be marked with MY THOUGHTS]
I'm kind of a ebay-holic and I collect way more Buffy stuff than I can afford, so many blog posts will be about collectibles.
