The preferred way of giving feedback on any aspect of the course via the SOFTENG1-95 electronic mailing list. You can monitor postings to this list (and responses) in the archives. You send email to the mailing list by addressing it to SOFTENG1-95@mjmail.eeng.dcu.ie.
If appropriate, you can give me private feedback on any aspect of the course, or ask questions etc., by sending e-mail to mcmullin@eeng.dcu.ie. I normally check this mailbox at least once every day, and will respond as quickly as I can. This is far and away the most reliable and effective way of getting in touch with me.
