writing "serious" letters using OpenOffice - what templates to use?

For letters in German I use templates like these:

• Privatbrief DIN 5008
• Geschäftsbrief DIN 5008
• Geschäftsbrief (nach DIN 5008)
• Geschäftsbrief 1-6 - gemäß DIN 676 (Form B)

And you can always "get more templates online…", as they say there – at "File / New / Templates and Documents".
(Da habe ich wohl die Sprache durcheinander gebracht. Na, muss mal überlegen, was ich damit mache.)
