Apologies to anyone who found spam comments on the site - unfortunately these things creep in occasionally.

I've culled the offending posts and disabled the user accounts that made them; if I've mistaken you - a real person - for a spammer, please let me know and I'll see if we can bring back your account.

Update: We're still getting spammed, so have disabled automatic creation of new accounts.

If you would like a new account whilst I'm resolving this, register for one, then email us (http://www.mathsinthecity.com/info/contact-us) with a message about the maths you're interested in.

Cheers,
Dave.
