[CentOS-docs] paging GlennMatthys

I have checked the ML archive for the last six months, and do 
not find a poster using 'Glenn' as their name.

I wanted to contact that author, but no WikiPage for him 
exists with contact information

Glenn, please contact me so I might discuss a page's future 
with you.

As such to address the issue more generally I made a small 
addition at:
 	Make yourself 'contactable'
