Keep it secret, keep it safe...

Just a reminder of something I re-post every now and then; if you know my main email address (the one at metamathics), please don't put it into any 'tell your friend about this' websites. Or indeed do anything with it except use it to send me email. If you'd like to send me info via a website or otherwise let strangers contact me, feel free to use denny@btsuck.org (which is already painfully well-known to spambots). So far my metamathics domain has managed to stay clear of spam and I'd like it to stay that way for as long as possible - ta :)
