Well, I do stay IC when I first meet people down here in the library. I ask them if I may of assistance. If they ask me how to escape, I point them in the right direction... if they come back soon after, still lost, I go OOC and ask them if they can see anything, at which point I will tell them about --fullbright or adjusting gamma. So, I am mostly IC, and sometimes OOC when helping with technical issues.
Oh, and as far as posting RP stories, I have to say that the library is a most boring place most of the time. Except for helping people, nothing really happens... well, sometimes I get the odd strange event in the dark flame room across the way.
