Welcome to JavaRanch (

), but have you both read the
naming policy? You must display first name-space-last name, no peculiar characters, not obviously fictitious.
I think Pinku Tinku probably is a fictitious name; please go to
"my profile" and correct your displayed name to match.
I think giotto - Otto G�l is probably a real name, but I think it is really Giotto-Otto G�l. If so, please go to
"my profile" and edit the spelling of your displayed name, because we can get fussy about - etc.
