Hi @vitya777 and I'm happy for you with this being your first post. It would have been good if we got some information about yourself so we could interact better.
Regardless and not knowing what you do, what colour hair you have, how old you are (get my drift) I have nothing to go on to speak about.
Oh well my invisible man ... pleased to meet you and wish you lots of success on steemit. Take care @racykacy
