Probably there is a mistake here since I have been a member of the IntenseCoin Channel in Slack. Probably the fact that username in slack can be changed at any time is the tricky point there
I have a similar situation. In a slack chat I have one name that I have not changed since registration. And in the table for the organizers for some reason instead of it is the name of the email on which I registered. ie letters before the @Please check the relevant sheet of the excel (with the usernames) if your username is there. If it is not, please check if there is in there the ID of your email. For example if your email was ABCD@gmail.com please check if there is any ABCD in the list with the usernames. So we can understand if we face exactly the same problem.
