You are absolutely right, and this is precisely why I added the OP on Skype; it just so happened that my first instinct was to reply considering others may have the same question I did (now or in the future) therefore I didn't visit his profile right away but instead I regretfully replied before it occurred to me to go ahead and visit his profile, which is exactly where I found his Skype username. Furthermore, when I mentioned being "happy to discuss this further on messenger," I was referring to Private Messages here on the forum, not Skype.
The entire reason I visited his profile was to figure out how to send him a PM (as I am newly registered on this forum) but I obviously do not have enough posts yet to send any PMs. Once I realized this was very likely the case, I started looking around his profile for any other means of contact and that's when I stumbled upon his Skype. So in conclusion, this is why I posted what I did first, but then ended up contacting him on Skype regardless. I hope you understand, and I am sorry for any confusion and/or frustration I may have caused (and I say that with the utmost sincerity — seriously).
Cheers.
