Extra functionality for plugin

Hi,
I was wondering if it is possible to get some extra functionality added to the Subscribe-by-email plugin? We have had a few lecturers (we're at Otago University, Dunedin, NZ) ask that the subscribe-by-email plugin allow emails to contain the whole post content and not just the excerpt details. Is it possible in a future version to include a variable for the full post?

Many thanks,
Kimberley
