Welcome to Steemit Cezary! I believe that most of us are not tech people or developers. There is something new here to learn every day and eventually you will understand how things work.

I see that you've been using Actifit already so you're not that new here :) But it's ok. Proper introduction is important for people to get to know you better.

I like your photos and I'm looking forward to seeing more of them.

BTW, your name is very interesting. Surname sounds German but I can't place your first name :)

I wish you a lot of fun here! I'm sure that you'll make many good friends and will have a lot of fun.

Have a nice day!
