Black thursday

Hi all!

Yesterday I suffered a great loss. All my data from this server went away… Unfortunately, I didn’t have recent full-backup of my blog so I needed to recreate some posts from WayBackMachine. That’s why most of pictures in posts from 2016 and 2017 is missing. Sorry for that. If you are interested in some exact pictures contact me, I can try to find them in my files.

I wish you more luck with your backups.

Bye!
