[CentOS-docs] would you please approve KenDreyer to edit SIGGuide/* ?

Hi wiki admins,

I would like to edit the content here:

https://wiki.centos.org/SIGGuide/Content/BuildLogs
https://wiki.centos.org/SIGGuide/Content/Mirror

Proposed edits:

1) The pages are really similar. At a glance, it's not clear whether
I'm viewing one or the other. Let's add text to clearly distinguish
them for newcomers.

2) The pages do not link back to each other, and they should, because
SIG members need to know how to distribute both test content
(buildlogs) and GA content (mirror).
