This extension will give you quick access to Prolific, no matter where you are. I've had lots of requests for some fast way to get to Prolific now that Facebook has taken away the quick application launch bar. And so here it is, with the added bonus that it will display your Prolific rating on the button.
Prolific is a word game for Facebook where you compete against others to make as many words as you can from the tiles on a 4x4 or 5x5 grid within a set time limit. It has a thriving and friendly community.
