Every text morph should have its own selector to
access its display text. So you may have
#text1, #text2, #text3 for three text fields.

The argument of 'accept' is a selector that 
takes two arguments: e.g. #accept:from:
The first argument is the string that is displayed
by the morph, the second argument is the morph itself.
The method is *required* to answer a boolean value:
true to accept the text or false to refuse acceptance.

Attached you find a small demo that may help you
getting started. Please have a look at the comments
in the methods.
