"maris",
Welcome to the JavaRanch, you appear to be having a problem with our naming policy - please read the section on bold below.
We're a friendly group, but we do require members to have
valid display names.
Display names must be two words: your first name, a space, then your last name. Fictitious names are not allowed. Please
edit your profile and correct your display name since accounts with invalid display names get deleted.
