Translation of eh in German

Sometimes you forget one word and this makes the entire sentence sound differently. That means that you need to read each email before sending it twice at least if you want to be on the safe side every time.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
I like music very much too. I prefer classic music, but rock is also good. When you come to my Berlin we need to out to concerts together and visit a few bars. They are all close to the center.
