OpenZika is a sub-project of World Community Grid. If BOINC has WCG as a project then you should be eligible to receive OpenZika work units. A simpler way to control the sub-projects is from My Contribution -> My projects and ensure OpenZika is selected.

I'll keep it short and simple ( I hope):
When you are signed into the forum just have a look close to the top of the website. There you can see the line starting with the logo and the words world community grid in bold colored letters (second line).
Follow this line to the right end and you'll see "My Contribution".
Click it.
Then go down the first column until yoz find "My Projects" and click it.
There you go. Enable the subprojects you want to support.
Don't forget to hit the save button.
Refresh in your boinc client and you'll be done.
Nothing complicated....

All subprojects list as a single entry on the client... WorldCommunityGrid. No transferring is needed. Anytime your client asks WCG for work, the project server looks at your profile selection and then sends work accordingly, based on momentary availability. If none are available the client event log will tell you.

That's just it - GridRepublic won't allow me to edit my projects. I've tried using both Firefox (which I know is becoming increasingly incompatible with a lot of pages) and Chrome.

It's alright; I'm uninstalling the software. It's too taxing for my MacBook. When I'm not using it, I can hear the fan going nonstop to cool the processor while BOINC is running.

Also, as I said above, they should have come up with a unified, easy to use interface by now. They've certainly had enough time. This piecemeal, open source approach is reminiscent of the early days of personal computing. They're trying to reach out to a wider community with software that is attractive mainly to academics, tech people and programmers. It shouldn't still, after all these years, be this buggy, nor should I have had to come to a forum to find out how to do these simple things. I may write an email, if I have the time and if I can find out to whom to send it.

Thank you all for your help.

I think this is a bad idea: you have time limit to calculate the task. This time limit starts at the moment when server send to the client a notification about new task available. If we use the same rules of attempts to retry the download as we have now for uploading there will be a possibility that this task will be not finished in time. And such kind of 'temporary issue' may not be resolved during long time as we can see on some projects.
