Hello,
I just noticed on the 'Downloads' section of the Therion website that the Slackware links is broken. The server that I was hosting the packages on has moved. The old server, juno.utc.edu no longer exists. The new address follows:

http://zog.utc.edu/~gqv812/therion.html

I'll hopefully be putting up a package for 0.4.0 soon, as well.

As always, Therion is an amazing piece of software and keep up the good work!

Sincerely,
Jonny Prouty
