Sorry, but mails from the list have ceased to come. I even do not receive my own messages sent to the list, even if my Maxima Subscription Options expect this. Would you please check my status in the list, or suggest me how to restore my subscribtion. At the http://www.math.utexas.edu/mailman/options/maxima/vidybida--at--bitp.kiev.ua, everything seems OK. Thank you in advance, -- Alexander
