Hello.
My name is Marcin. I am a Wikipedian since May 13, 2015.
My interests are: aviation, history, computer science, radiocommunication.
I try to supplement existing entries and illustrate Wikipedia articles.
Minor mistakes happen on Wikipedia, but they are eliminated.
As Joseph Conrad said : It’s only those who do nothing that make no mistakes.
