Nice!! I'm always glad to see someone expanding the jq lib universe :) Anyways, I know its in the early days but I'd definately suggest adding localization as a high priority next step. Here in europe, i'm always at a bare minimum of two languages on every form I make, so when frontend libs are hardcoded with one lang I can't use them. You might already know about it but for a howto on localization check out this other jq form validator (https://github.com/jzaefferer/jquery-validation https://github.com/jzaefferer/jquery-validation). Overall, good job! Lastly, I'd also suggest allowing option passing via $.extend.
