Here is a list of everything I can remember that you can do in cow.
create objects
create objects made of a material
objects inherit code,worth and colour from their material object
objects inherit code and colour from their 'class' object
create objects called/named something
create objects of worth
create objects with descriptions
create objects which are auto-coloured if you name a colour
create quantites of objects
get|drop|push a quantity of objects
increase|decrease the quantity of objects
paint objects
lock objects so they cant be got, painted etc..
lock objects with keys for later unlocking with same key
describe objects
pose objects
write in objects
assign a gender to your objects (and yourself)
put objects relative to another object
position objects in the map view
assign images to objects for look, list and map views
code objects to react to triggers using COWScript
(each command (create,look,say etc..) is an object coded in CowScript)
link objects together turning them into doorway objects
get|drop eat/drink|burp objects so you are carrying them
view what you are carrying
wield/carry/use objects direct from your inventory
give|contribute objects to other objects
hide objects (so they cant be found unless your in the same location)
find objects anywhere (which are not hidden)

list modified objects
add feedback|comments to|on any object
build new locations (which are just objects you can go into)
build new doorways to locations

open|close doorway objects
face doorway objects
say text to other players in your location
(including, but not limited to, ask,sing,think,ponder,mumble etc..)
do things for other players to see in your location
shout text for others to hear anywhere
any command can be done 'loudly' so everyone hears it
any command can be done 'politely' so you gain nice points
point|ping|gesture at objects (initiating a ping in each browser)
prompt users with clickable commands,googles,wikipidia and websites
read about every command in the books found in the library
read the Daily COW for the latest news
use the postal service

subscribe to an RSS feed of the Daily COW news
subscribe to an RSS feed of any list of objects
use a spell-checker when writing in an object
use a rich editor (wysiwyg) when editing objects
embed images in objects
embed sounds in objects
embed clickable commands
embed quick google links
embed quick wikipidia links
do multiple commands in one go by separating them with 'dot space'
recall last commands (different UIs handle this differently)
