I have been using the online MOM documentation quite a lot recently, and I have to say it's finally looking like a top quality set of guides.

For those who dont know its had a recent update in August and has a new look and feel and has had a lot of good updates.

With MOM 2005 being one of the more recent products in the product line I knew that it would take some time getting the docs anywhere near the standards of SMS's very impressive line up, but I do feel now that is starting to finally come of age.

Big up to the documentation people, you can be proud of a very comprehensive and professional line up of docs in the catalogue, with very easy to use and navigate online versions.

Just need to sort the management pack catalogue out now ;-)
