Thank you for giving information to join online.me
I didn't tested site but just browsed site for few minutes and I find these observations and need to improve

We must trim email after user input and it should be case insensitive for making it user friendly.

Look into it: Not getting loaded timeline contents by ajax on timeline from dropdown after posting first post on timeline, later its working okay.

Look into it:: I found few posts are not getting responsive in sidebar.

Look into see more it: On album pages images not getting responsive

Site must give feature for profile cover and it should should be set option to move images and set it properly, it should be responsive also.

Including my last comment feature requested.
