I registered and could not check my notifications because anything I click it keeps asking me to upload a profile picture.
Thank you for your question, @engrjoe. That was not an error or glitch in the site. Hidira has been originally desinged not to allow users use the site withouth having to upload their profile picture. This is because having so many profiles without pictures will make the site look dull. Also we discovered that profiles withouth pictures meant that the user might not be serious or might be willing to use the site for malicious purposes.
I hope this answers your question?
