Hello, Banet123! Welcome to Wikivoyage.
To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. If you are familiar with Wikipedia, take a look over some of the differences here. Pashley (talk) 16:43, 26 June 2018 (UTC)
Hi, Banet123. What's the travel angle on the Sava River? Keep in mind the differences between an encyclopedia like Wikipedia and this travel guide, and have a look at Wikivoyage:Bodies of water for some relevant things to think about. Ikan Kekek (talk) 06:58, 7 August 2018 (UTC)
