i didnt get to go through to the specifics and what not, but its good enough for what it is. hopefully you can get good ranking and a ton of files to make your site viable. good luck!
The form to upload the files is not that user friendly... The host it button should be little more visible Put some nice graphics
It is ok. One big problem is that it is not very easy to follow because your text is to small. You have to much going on in one little crammed area. If it were me I would just make one big upload section at the top and then all the crap at the bottom. But make everything bigger!
page rank related with your domain age too bro, but optimization search engine will help you to improve it
do link building more and more with high pr site in your site niche.i did it for one of my site page rank incease from 2 to 4 in four months.
bro.. u only have about 75 back links in your website. Make quality back links to as many as u can from good websites. Just wait for the next google update and you will get appropriate page rank according to your hard work. My site s 4 months old and i got page rank 3. Best of lucks
