Is there any way for an end-user (myself) to download all private messages?

In a previous version of the forum software (a couple years ago) I tried several website downloaders, but none worked properly (only a couple supported logging in). With the upgrade of the forum (4 months ago) there is now a PM limit. Rather than sort through everything, I'd like to download all PMs so they are usable offline, and then delete everything online.

I though I would ask here first, before doing a bunch of searching and program testing.

If it matters, the forum is http://www.larian.com/forums

Select all (page based), Email selected PMs.. delete

{rinse, repeat}

But you do need an upgrade to 7.3.x for that. He is still using 7.2.2.

then upgrade
