Dear MWG Fan Community,


Now that MWG 7 has been around for a little bit and we have plenty of experience with the dos and don'ts of this most powerful web gateway ever, we figured it was time to get some best practices out there and spread the word about some of the awesome features MWG has to offer.


Below is a collection of documents written to help you understand the MWG better and hopefully cover some of the common cases you as an Admin experience.

Part of the idea is to collect feedback (No, not the this time ) from you as community contributors and keep improving and adding to the collection. If you have a topic that you would like to see covered or learn more about, please let us know in the comment section below.



We hope you find this collection of best practices and common cases interesting and ultimately helpful in making your admin life easier. Let us know what you think and keep comments and suggestions coming!
