We already have quickterms and SICs and whatnot, but, it'd be cool to have Database Terms, that you could buy (expensive portable ones that you can use anywhere, like quickterms, and cheaper stationary ones that would have to be 'set up' by the player- sort of like laptops and desktops) - You could have folders and type up text files to put in them, a sort of filing system for your records.
Of course, you may have noticed I'm really getting into the Judge gig, so you're assuming I have a Judge angle on this, right? Of course I do! It'd be great for filing reports by date/crime, and tags (sort of like html metatags) with the perps' names, et cetera, so we could look up old case files and do some m@d investigating!!!11 Filing reports is really starting to fill out the Postingboard. And, another advantage to this would be that, by the time the Matrix is ready, there would already be a wealth of player-generated information for netrunners/deckers to steal and sell.
