i'll go on, at length given a chance on this sort of topic.

i'm sure i have already here in TEG...
as a side note, if i ever post a picture here it is very likely i'm linking to it from some place (likely a project) on my website (and a non-thumbnail version of the picture will also be available there):

here are some of the details:

the shorter answer is, yes, simple system, worms, 10 buckets this year, last year i had 16 buckets and one larger square bin i used, but it was too much space taken up so i downsized, covers (to keep the worms and bugs in or out (or both))... no drainage holes. i control moisture levels by evaporation and only adding some wet items once in a while and extra water if it gets too dry. the worms will do fine in a bucket of dirt and organic materials to eat up until nearly saturation, but it is very heavy to move and smelly (like a swamp) when emptying so i try not to get them that wet.
i dry veggie and other food scraps or store them in the fridge until i can add them to the buckets.
melon/melon rinds are worm crack. those i put in fresh and they're gone within a few days except for a bit of skin left.
i restart the worm buckets each spring from some of the worms i keep back, so i can't use the full contents of each bucket, but about 20-25% are used to restart and then the process repeats each year. so what you see there is one year's results and one bucket of 10.
