Jürgen L Good catch Sir. I was going to write the same words but when I read that you have already caught TW then I could just hit like button on your post 
T W for your query I just want to say that If someone can't show his identity here then its better for him to just take help from SCN. If someone is going to be a group leader then he must come here with real name and identity because his followers and fans want to know him. May be thats why most of the mentors and group leaders here are with their real names.
Thank$
