Wow, that is also a nice site. Looks like Preev.com is gone giving opportunity for people to develop a similar site and hope to gain more popularity. The other day I was reading [ANN] Preev is down, Im happy to announce the official launch of Pnnv.com.

I would suggest you add some more features to the site, like more currencies to convert etc. Also, it will be good if you do decide to promote our site through campaigns on bitcointalk.
