Unfortunately that site doesn't seem to function (tried it in Chrome and Firefox). Clicking any of the menu items keeps me on the same splash page. Maybe the problem is on my end, but I can't get it to work.
Edit: It was me. Didn't understand the log-in box. I'm still interested in finding someone on here if possible, there's not much volume (or any that I can see) on that site right now.
Hey. I'm the creator of Ubitex. The reason there isn't much volume is that there isn't much volume! Just create an order, even if it's never filled you'll be helping bootstrap our site.
I posted an order. Definitely would be nice if your site is able to pick up steam, and I think it will if BTC continues to catch on.
If I could make just one suggestion it would be to explain somewhere about OpenID. I'm more "tech savvy" than 80-90% of my friends (still an idiot compared to the other 10-20%) but I didn't really get it at all as I hadn't heard of it before and there's no spot to put a password.
Also, the "become a seller" makes sense, but a lot of people won't realize that can also mean a seller of USD (aka, a buyer). Buyers of BTC will tend to be the less experienced users who are less likely to click that and realize they can buy. Maybe you could change the heading to buyer/seller. I get what you were going for, but I'm worried it's counter-productive.
Anyway, great site. Very simple/smooth overall.
