Some issues...
1 - There is something wrong with the user's session management, when browsing pages the account name on top-right always change to "login register" links;
2 - The "claim you offer" button is not working, there is an error in its loading;
3 - The link to open the account options (top-right) is kind of small, I always click on the name thinking that is going to open a menu and the page is redirected to the Dashboard;1 vote -
Pronunciation of 'Data'
Hi, this could be a feedback but please bear in mind it may be very opinionated. I checked with several colleagues and none of them are comfortable with the pronunciation of the word 'data'. For me it is a very distracting part of the videos and I decided to turn off the audio due to that...
I did of course look it up and the pronunciation can be:
1. 'Big day-tah'
2. 'Big dad-ah'Both are correct. The second one is however very uncommon and can be experienced as very distracting (in my opinion). I am writing this feedback to…

Confusing
From your video "To do this, you can use the Share button,
which lets you share using Email,
by Downloading as an image, presentation, or PDF file,
using Twitter,
or through a link that you can provide"When asked on the review what the options are for sharing analysis I entered in email, downloading as image, presentation, or pdf file, and twitter, which told me I was wrong. I then though that the link you provide could be Instagram so I added that on to my answer, which was also wrong. I've noticed this happen a few times so far…

Should allow to login using username
I think, it'd be easier to maintain & use the account with multiple options available. it's good that you provide multiple email options, but it'd be great if your provide to login using username. What is the use of a unique username if it can't be used instead of your email id for login? I changed my email id & was unable to login after that as your database didn't receive my other id. So, that made me lose all my progress with the previous account. Thank you!

Support for more web browsers than just Chrome
I was not able to access the Lab content in the R101 course when I used FireFox. Only when I used Chrome was I able to access the lab content. This is a limitation of the Cognitive Class Labs/Data Scientist Workbench. I also noticed that Seahorse only supports Chrome. I would like to see support for more browsers, and not just Chrome.

Astonished at the choice of instructor for a core course - Hadoop 101
Hello,
I am simply astonished at the choice of instructor for such a vital course as Hadoop 101. Asma Desai's reads at rocket speed and the narration is terribly incoherent.If I have to pause the video at an important instant, before I can click the pause button, she squeezes in a dozen extra words. Now I have to move the slider to a few seconds back and re-try the pause operation.
This has contributed to an extremely annoying User experience while taking Hadoop 101.
Please replace the Hadoop 101 course video with someone who knows how to teach. I…

show the correct answer and explanation why when I get a fall for a specific review question in the final check
Hi, I really like the courses provided by the BigData University. However, I find it is time-consuming to go back to find the answers from the previous modules when I got a fall in a review question. Therefore, I suggest you could automatically show a chat box after I click the FINAL CHECK, so that I will get the full explanation about why this option is correct and why that option is incorrect, no matter I pass the final check or fall. Many thanks. Hope I have present my suggestion clearly. If you have any question about my suggestion, please…

The review question in the Demo section is incorrect
The review question posed in the Demo section is actually one of the answers. The question can be inferred from the other answers but needs to be corrected.
