That's where I saw it! It was at the top for a while as you logged in. I think I probably ignored it. So, there's no way to turn them on once you're in the app? I'm looking now but nothing leaps out at me. :)
So, I need to clear cookies first, then log back in? What if I have multiple pages up? Will I get beeped every time the other account gets something too?
I'm not exactly sure how to get it back.
Yes, I occasionally have other people's SteemWorld pages up and get notices from them...
In case you've just ignored the hint and you didn't click on 'no' (not allow notifications) it should show up again. The option 'Desktop Notifications' in the settings on SteemWorld should not be set to 'Disabled' of course. Depending on the browser you are using, there should be a section for notifications in your browser settings where you can configure the behaviour for each website.
So, I found the notification settings for my browser, and I think I've found the desktop notifications under settings. The browser is now set to accept and the site settings is set to show all. Thanks for your help.
