As well as reading the webcomic through the Smack Jeeves website - You can now follow Giant Rhinos In Space on Ink Blazers (formerly Manga Magazine). At the moment I'm updating with 6 new pages every Friday to catch up with when Chapter 2 is scheduled to go online.
Chapter 2 will return on Friday 2nd May 2014 with the first 5 pages
The webcomic will then update with 3 new pages at 12noon* every Friday!
*As far as I know Ink Blazers does not have a way to schedule update times so updates are likely to be out of sync but probably within a couple of hours and by no more than a day.
