Much Obliged

A helper recently submitted some content to me.  I could not open the file.  I advised the helper to resend the material to me, but to compress the file before sending it.  The helper obliged.  I opened the file and imported the content.  I found a mistake.  I advised the helper to correct the mistake.  The helper obliged, and sent the updated material to me.  I found another mistake in the updated material.  I advised the helper to correct the new mistake.  The helper obliged, and sent the updated material to me.  I could not open the file.  I advised the helper to resend the material to me, but to compress the file before sending it.  The helper obliged.

This is pretty much how the development process goes.
