One account for both Income and Expenses possible?

[Norbert Klein]

Thank, Maf,

your advice was very clear and helpful - I rearranged what I had used 
before accordingly.

But you advised me also:

I am sorry - but when I started my mail with "One account for both 
Income and Expenses possible?" I was not aware that that this was an 
existing thread.

How can I check - when I start to write something again - that what I 
want to use is NOT YET an existing thread?

Thanks for any advice and help.
