It's pretty hard to find task requests published by project owners. It doesn't show right away on their blogs.

Here are the steps to find a task:

First, go to a Utopian that is a Project Owner/Maintainer, I would use myself as an example here:

Once you're on that user's page, you need to press the Projects tab in their profile:

This shows a list of all their Repositories or Projects in their Github Profile:

You need to simply scroll down and find the Project you were looking for, I'll use my Oh Steem game for this:

The All tab will show all contributions and tasks under this project, so to sort it out, press the Task Requests tab:

This page will have an All tab as well, and tabs separated depending on the tasks published.

Simply scroll down or use the other tabs to sort the Task Requests.

Just tap a Task Request to open it and get more details.

That's how you find specific tasks published by Open Source Project Owners or Maintainers.
