New and Notable
Unpack the zip and run the Salvo executable. Add a news server, add newsgroups then doubleclick a newsgroup to read its messages. It is pretty simple but here is a three.three minute instruction without audio. Send me a mail on my gmail or tweet me at twitter if you download this. You can send bug reports and feature requests also to one of these addresses.
The code has a pluggable server and persistance implementation. The reference persistance impl uses the local file system and stuff is stored in a .salvo directory in your home directory.
