By the way, what you have extracted as my "username" is nowhere in my profile (can not understand where did you find such information!!) and when you search in slack directory with the "username" you have extracted, it finds zero results. However if you search the directory with the display name (the @name I inserted in the airdrop form) which is the proper username in Slack nowadays, it gives the proper results. I can not write it clearer than this, i believe, so am really sorry if you guys cannot understand.
Sounds like a good (and the only fair) solution to me. The IntenseCoin guys needs to re-verify all those that haven't received an airdrop because of a Slack username issue and compare the submitted @username with what's shown in that "Slack Directory". I'm not on Slack, but I guess this is some form of follower list. Finally send out the missing airdrops.
