View Mature Content

LOL that same thing just happened to me like, 2 minutes ago, and I had to go back and change my preferences. I have NO idea what it is that they consider "mature content" on this site, since I was responding to a question about being tired all the time! I didn't mention anything except for vitamins, caffeine, and milk! I don't think that's "mature content", but oh well! I'm sure I'll figure it out eventually...

I was wondering that too.. I have had a few post that I cant read because I have not selected the mature content in my preferences, Generally though its a list of words that could be construed as mature content

There's a mature content filter that's triggered by certain words in a discussion. If a discussion contains any of these words people who have their mature content filter turned on won't be able to respond. Don't worry, most of the discussions that are tagged as mature content are pretty harmless.
I hope I explained that ok:)
