Newsletter unreadable

Although this might not be the best place to post this I can't see how else to sort it out (which is part of the problem).
I subscribe to the FSM newsletter and look forward to it, but this month it was unreadable (not because Paul Allen was guest editor -not - but because it was closely spaced type tightly packed. Presumably it is available in html, but how and where do I change it. I really think all newsletters, wherever they come from, should have a link to manage the subscription at the end and the FSM should set an example (the http://sys113.3fn.net/mailman/listinfo/fsm_newsletter link gives a 404).
Apologies if I'm being excessively thick but I would like to sort it out.
Nonetheless the site is very interesting and informative, so thankyou one and all.
