newsgroup message threading

[startrak]

Hello All

I've been writing my own newsreader client app, from the socket level
up. I've done most of the standard stuff like downloading newsgroups
and so on. Now I'm finding the message threading part very difficult.
I've looked at the algorithm on www.jwz.org. It says a hash table is
needed could I simply use THashedStringList, and add message objects
(structs objects) in there. If that is correct how would I go about
retrieving the data from it, i.e. get back the object I initially
inserted into the THashedStringList.

Thanks in advance for any help.
