Notes to self - 005, Get it in writing - even if you have to put it there yourself

As I wrote a while back it is always a good idea to get important agreements in writing - Today I just had to remind myself that - especially in these days of electronic communication - there is always the option to put it writing yourself.
As a last resort - e.g. if an official protocol would be taken as an offense - I take the tangential approach as in "When we agreed on we also mentioned - would it be OK for you to treat these separately?" thus getting a written - and circulated - record of without offending my negotiation partner.
I most cases though it should be quite OK just to communicate openly and agree on putting the agreements in writing just to make sure that there are no misunderstandings.
