One of the best things you could do would be to submit patches against the core library set where documentation is missing. Starting with things in base, array, containers, directory, filepath, pretty, time etc.
That would likely help the largest number of users.
Patches to these libraries can be submitted to the libraries@haskell.org list.
To elaborate ever so slightly on what Don said: A lot of libraries only have type signatures for functions in the libraries as "documentation". What's missing is English descriptions of what the functions really do. You yourself may not know what the functions do, but you can learn by experimenting with the libraries (writing little programs that use the functions) and by asking on this mailing list (and reading old posts in the archive), if necessary. It would be really useful if you decided to put time into this. Thanks in advance!
