He's pretty much the exact opposite of a troll. Never posts and just works on making NEM better behind the scenes. If I'm not mistaken, he is responsible for making the NCC look so damn sexy!
My suggestion to Loi.Tran, take the .ai file from here:
https://trello.com/c/42ucSEVL/116-interim-logo-kit , and make the logo better (if ya got the time). I personally don't think the logo is too bad, but I do think the border is a bit odd though.
This time I'm quite busy. Reason why I didn't start build some more logos because I find the way to the final logo seems not very clear, and I cannot spend my effort without a specific goal. Until we're planning for a logo contest & official public vote, I will be ready for that.
My logos are not in that list. Not sure whether I can post them here until someone confirm me on this. I was not frequently active in bitcointalk.
You should be able to include an image that's online by just pasting it into a post, and then surrounding it by an img tag, which is in the top left corner when creating a post. You might not be able to do this because of your low post count, but I am not very sure.
