Eva Bloag!
http://evandachar.blogspot.com/The blog isn't publically posted ICly, as many aren't, so if you want
your character to have read it and know what's in it, all I ask is that you get in touch with me and provide me with a believable explanation of how that tallies well with "established reality" of events at the time. (Remember, my character is IC all the time in Eve - for me, there are no blank spaces where I don't know what my character was doing. "You broke into my house and read it? While Evanda and Cia were there reading the naughty bits to each other and giggling? OK fine... Where do I live?" as an example of what might be a clash with "Established reality" for me.)
On the other hand, if you want to subtly use it to give yourself clues on, for example, Eva's current mood and generally flesh out interactions with the character by creating a more vivid picture of her for yourself, by all means be welcome. So long as I don't walk away with the feeling your character is psychic, I'm happy.
Or it's there just on the off-chance you might enjoy reading it.
