Seconded. I would like an option to download PMs or postings, signed with GnuPG. Because unsigned they would later be worthless as proof.
https://bitcointalk.org/index.php?topic=235794The option to fetch unread posts as XML would also be really helpful.
GPG signed will be great otherwise just simple pm to text/html file export option.
It will save alot time if you need to find some old pm.
