Please don't just blindly put real names in to the database. We have outlined our rules of thumb when we think it is to okay publish the real names here: https://demozoo.org/pages/demozoo-standards-and-practices/. In your particular example, "A+B Soft", the real name is already present in the database but it is not visible to regular visitors, because we cannot say with confidence if this person would want to have their name shown in the context of a demoscene website.
Yes, and Different name, is just for another handles. Some sceners had been performing under more than one nickname.
All right, aknowledged. Didn't think of that.
draxxx: I just sent you an e-mail :)
In addition to what Creonix said, some sceners have release their entries BOTH under a nickname and under their realname, in which case it would of course be okay to add the realname as an additional nick (which has been done in several instances where sceners have done exactly that). However, if they didn't explicitely release under that name, then please don't add it as an additional name.
