Meg has come up with an idea!
You may have noticed that like a lot of bloggers I use a - quite a lot in my writting, somehow it seems to fit the conversational style I am trying to adobt. Where () seems not uite right and; a bit formal I use a -. Meg uses a tilde ~ and proposes that we all adobt this as some sort of "secret signal" in our e-mails etc. see what she says in full here.
I am not at all sure that this will work, but since I agree with Meg that it does look nice, feminine, and informal I will start to use the tilde.
