Hi Hrenrut, and Welcome to Wikipedia! 

Welcome to Wikipedia! You may have already been a long-term user or contributor, but if you haven't been welcomed before, please consider this a welcome. I hope you enjoy the encyclopedia and want to stay. As a first step, you may wish to read the Introduction.

 Additional tips...  

 Please sign your messages on talk pages with four tildes (~~~~). This will automatically insert your "signature" (your username and a date stamp). The  button, on the tool bar above Wikipedia's text editing window, also does this. 

 If you would like to play around with your new Wiki skills the Sandbox is for you. 

 Good luck, and have fun. FWiW   .
