I got your emails of the 17th/18th July. I responded via my normal email (which I thought had been "unblocked" because I didn't get any 'bounces').
Anyway, I just emailed you through my webmail with my previous responses. From now on, I'll simply answer any emails I receive from you (actually all of Canada it appears) through my webmail. That way I should be sure you're receiving them.
(Please let me know if you don't get the email I just sent).
