[Equest-users] Attachments in the Archive (was Re: Zoning Issue)

[Jason Glazer]

The archives now include links to attachments using the 
original names of the attachments.

Nick's email is at:

http://tinyurl.com/2g964sc

If you scroll all the way to the bottom, you can click on 
the links and see all the various graphics that were attached.

I requested this change in the way archives work from the 
web host that hosts onebuilding.org.
