Hi,
First of all, congrats on what I think is the best charting platform I've seen to date. I just thought I'd mention that I was one of those users that kept seeing the "Loading..." screen all the time and couldn't get past that. After much troubleshooting and using my protocol analyzer, it turns out that it's because my firewall blocks port 8080 outbound by default. I imagine this is also the case with many users on computers in corporations. I've known many companies that only allow port 80 and 443 out and block everything else - quite literally. 8080 is typically associated with proxies and is blocked so as to prevent people from getting around other firewall rule restrictions.

I'd like to suggest you put some very basic instructions on your "Help" page on your website with the basic firewall rules required. Also, on the loading page I was seeing, it said that perhaps it wasn't loading because I had more than 8 connections established (which wasn't the case). So perhaps that's another place where you can post the 2 liner firewall rules required.

I believe the requirement is something like:

Outbound (to internet) Firewall rules required:
1) bitcoinwisdom.com                              TCP/HTTP port 80
2) 184-22-51-146.static.hostnoc.net         TCP 8080
(184.22.51.146 also resolves to s2.bitcoinwisdom.com)

Cheers and keep up the awesome job!

PS. An even better idea is to stop using port 8080 all together, is it really necessary? Can you not just stick to 80 on your second server, or perhaps use 443 with SSL encryption if your servers can bare the load?
