The "Artist" and "Scribe" are quite useful the campaign, and I also agree with lisardggY's suggestions about transportation and centralized documentation to follow the game.  That said, here are my additions:


While the specific game escapes me (I believe it was a White Wolf book), they suggest offering XP to whomever brings snacks for the table.  
As a personal belief, if for some reason I'm not able to run my games in my home, I tend to offer a small bonus to the host of the game session.
Fleshing the Backstory: Most of the players I encounter have their central theme designed more like a video game than actual people until they play for a while and get some momentum.  Thus I have started offering rewards for people who come to game with meaningful data on their character.
Stationary Supplies can be a very eroding stock.  Anyone who consistently has pencils, erasers, especially blank char sheets, quick references, etc.


Side note: Just make sure that the XP bonuses don't ramp up too quickly.  In some games the balance gets upset quite quickly even with the smallest offerings if they happen regularly.

In-game rewards for game-related work?
I'm kind of a newbie to this so I could be missing something really obvious, but I'm having trouble getting specific libraries to load with jQuery 1.7 in noconflict mode using jqmulti. I'm working on a theme based off twitter_bootstrap, and the bootstrap.js library is dependent on more recent jQuery. I've got jqmulti recognizing and loading 1.7 if I check "load even if no libraries are assigned" but when I have that unchecked and attempt to use hook_jqmulti_files() to assign particular libraries, nothing happens.

This is what I have in my template.php:

function regent_jqmulti_files() {
    return array(
        'sites/all/themes/regent/bootstrap/js/bootstrap.js',
        'sites/all/themes/regent/bootstrap/js/bootstrap.min.js'
    );
}


but when I look at my rendered html, the library is loaded, but nothing about noconflict mode,  and jQ 1.7 is nowhere to be found. I'm sure I'm missing something basic and stupid, this being the first time I've tried to set something like this up.
