[Mapserver-users] HOWTO: 24 bit png on WMS interface

[Kari Geurts]

Hello MS-Users,

I wanted to let you know that we have revived and revised the “Add a
Comment” line on the mdp documents (located at the end of the
document). This is a great way for users to give feedback to the
documentation authors and help keep the documentation accurate and useful.
When a user makes a comment the message is sent to the author and they can
then evaluate it and add it to their document. 

The message below is a good example of how the “Add a Comment” line could
be used. I encourage you all to use this function to help make the
MapServer Documentation Project more successful.

Thanks,

Kari A. Geurts
