What should I review? There's nothing on it.
There's no About section
No Register link (though
http://www.sephid.com/sp/register/ works)
The register didn't worked (error 500)
There's no visible functionality other than a search of 2 sample data items
Once you login (the register DID worked, even returning a 500 error) there's nothing you can do other than search those 2 sample data items.
The search functionality has a green-ish box (while it's retrieving the search results) that flashes for less than a second, making (if possible) the dead simple and only functionality of the site (search 2 sample data items) something somehow confussing (what it was saying? something relevant? why some elements danced in the page while the search was performed?)
My review? That I spent more time reviewing the site than the time it took to build it.
My advice? Put your shit together, plan more, add some useful functionality, test it and come back again.
