That's great that you want to start writing scripts! I think the
duplicates script was already started by Patrik Karlsson, but he may
comment about that. duplicates is a bit more complicated than other
scripts, because it will probably have multiple rules: a hostrule and
portrule that record information for detecting duplicates, and a
postrule that compares that information. That said, there is probably
room for more than one to work on this script, because of the multiple
duplicate detection mechanisms that are possible.

Some other ideas on the script ideas page don't require any special
technique--they just need someone to spend some time understanding and
implementing the protocol.
