The video course that I took to get started in Drupal did a wonderful job of showing me how to create a custom block and put it in an area on my webpage. Unfortunately, I have since found that except in rare instances it's the wrong thing to do.
The "right" way, at least as far as I am concerned is to create a content type and then create a view as a block. Then place the block where you would have placed the custom block.
A regular customer called. He noticed that he had a lot of Sent Items in his email on his phone. Not understanding how Microsoft Exchange works, he proceeded to delete Sent Items from his phone - several hundred items that were a record or legal transactions.
It is an understatement to say that the customer was somewhat disconcerted when he looked for the sent items on his computer and found that they were no longer there and not in his Deleted Items folder (oops).
This seems interesting enough for a first post.
I had previously spent all afternoon trying to figure out how to restore a customer's email address auto-comlpete function to a new computer. He had subsequently sent the computer back to HP, and the nice folks at HP had reinstalled the OS even though the problem was that the speakers jack had failed.
