Unsure if should be here, though it's related, so...
Just went to my email and saw that "Mod Chanti" sent a reply the first day of June, asking for where to put the free membership. This is rather unusual, to me at least, as the past competitions were all through my Runescape mail to make the confirmations, if I recall.
Not sure of the distrust I have after looking at it, same email ([email protected]), seems to be the first email I sent that I thought the attachment didn't work and resubmitted, a Disclaimer and such all seem to be in order to be the real thing.
Just posting this now to also at least have other winners know where Chanti replied to, if they also have one and didn't know.
Tired at the moment to think it through...
