I've updated 'help sex' to be more clear about what is and isn't allowed. The gist hasn't changed but I wanted to flag one thing that there has been some confusion around.
It is 100% OK to do sexy time talk on the SIC as long as it doesn't violate any of our existing rules. HOWEVER-- admin can see everything sent on SIC, be it public, encrypted and private. There is no way for us to mute a specific person or conversation. The SIC is also NOT ICLY SAFE as many of you know, and it can be monitored ICly by other characters. If you do not want your private moments read by anyone, you should do them in person, in private.
When it's done in private, any admin monitoring you or the location will simply stop monitoring and give you privacy.
