just found a search mechanism that searches individual LJs... it's not complete, but if you're looking for something that was posted within the past month or so, this'll do.
i also made one that integrates the major vegan communities, but i don't know how to make it so we have the option of choosing only vegancooking. :-( that's unfortunate. anyone know how?
thanks to bobbymcr for the hack.
feel free to change it to suit your own needs.
