The manutal method of creating a form letter described in Creating a form letter provides the most control over the result and is therefore recommended. If you prefer to use the Mail Merge wizard, the technique is described below.

Before starting you should note the following limitations, current in OOo 3:

• In Step 4 creating the salutation only allows the sex-related Mr. and Mrs. It makes no allowance for Miss or Ms, nor does it permit sexless addressing such as Dr.
• Again in Step 4, the General salutation is not editable and the default values are somewhat limited.
• In Step 5 the layout is idiosyncratic, with paragraph marks all over the place so as to space the address block frame and salutation. Creating a professional looking document requires significant editing.

If the above limitations are not a hindrance to you, then open a new document with File > New > Text Document and start the Mail Merge wizard using Tools > Mail Merge Wizard. The wizard opens, as shown below.
