Adding a little realism - Log Book

[Reece]

Just wondered if someone had done a mod or is it possable to have a log book where you can enter dates and events?
If not has anyone got a picture of a page from a real U-Boat log book that they can post? I can then create my own log book.

I figure entering events such as sightings & action taken, depthcharge attacks, running silent, sitting on bottom, damage, Injuries & deaths etc etc would add a little more realism & could then post screenshots of your logs!
This may have be done already but would have to be done "in game", opinions & ideas please!
