Hi I have a client that would like to run a Wiki for his staff, it is only for internal use, and not the general public. He wants to store internal policies and procedures, as well as sharing industry updates. So I am looking for a recommendation on software to use, something where we can categorise articles and allows for uploads of documents etc.. One of my main prerequisites is ease of use. The client is NOT very web savvy, but can drive Wordpress quite well. Something as easy as that would be ideal. Thanks in advance!
