hi,
i shut the bookbrg.com website down after i started working as a software engineer for one of the major ota. I apologize that i did not get a chance to put some messages on the website about shutting it down.
Here's another website my friend built. It has similar feature. Please check it out.
https://www.flyertavern.com
i believe it is still under active development and you might see some bugs there......
Cheers!
