A number of students and colleagues have had trouble with the SPAM protection using the PGCC system. I have established a separate e-mail account on gmail to handle this problem. The e-mail address is
prof dot pgcc dot egr at gmail dot com
Remember to convert the word dot to an actual dot and the word at to the at symbol. This format is used to prevent the acquisition of my e-mail by automated seekers of addresses for nefarious purposes.
