If you want to contact me, the most efficient way is to send emails to me. I will check my inbox every 4 to 5 hours, so you should get my response pretty quickly unless the mail system moves your message to the junk box, which I usually will clear directly after a quick check every week (so it's possible that I can't even see your email before it got deleted).
If you have not got my reply for a long time, check your junk box!
