I am using OOo 1.1.0. Under Help for OpenOffice.org Writer in the Index, there
are two entries under mail merge.  They refer to creating/using a "form letter".
 The Creating a Form Letter instructions go into (now) unneeded detail about how
to manually create a form letter.  But there are some problems with it:

First, it says the first step is to create a template document, which can be
misleading because OOo 1.x differentiates between a Text Document Template
(.stw) and a Text Document (.sxw).  So, I (following the instructions) went to
File - New - Templates and Documents and found that there were NO templates
there. Then I thought I'd have some help creating one and I went to File -
AutoPilot - Form... and wasted some time trying to get the resulting Form
(seemed like a "form letter" to me) to be formatted as I wanted (which was like
fields instead of form functions).  So, maybe you could consider not calling the
Mail Merge function a form letter and/or try to prevent the above mentioned
confusion by clarifying things more thoroughly.

Second, under Printing or Saving the Output of a Form Letter it says "To specify
the data to include in a form letter output: 1. Choose Tools - Mail Merge to
open the Mail Merge dialog."  When actually it should be (in this context) to
call the data source view and click on the Mail Merge button on the Database
bar.  Try each way to see the difference....  BTW, the help for the Database Bar
calls that button both Form Letter and Mail Merge (because the button used to be
only called Form Letter).

Third, explaining the details on how to manually create a form letter is
possibly unneeded because when you choose Tools - Mail Merge it guides you
through each of the steps almost like an AutoPilot.  So, I think that it would
be good to change the listing under mail merge in the Index to show how to use
the Mail Merge tool, and have a Related link to Creating a Form Letter.  Also,
it seems like it would be good to include something about the Business Letter
AutoPilot, too.

There are other areas in the OOo help related to this topic that need updating
and I suppose also in other areas of the OpenOffice.org product that have changed.

Also, the descriptions on this category/component(documentation) are not clear.
 I am assuming that the manuals subcomponent is refering to the Help file
included with the OpenOffice.org product.
