I found the last time I went, the event and the company completely disorganised, and for an international event rather lacking in the ability to communicate.
I tried to sign up to the same event mentioned above, completed the form online but had forgotten my password. Nowhere on the website is there a password reset button, so I filled in a support ticket on the Wednesday before the event. Waited, and waited no response, so Friday afternoon I used the number on the site to try to call, 3 hours of hitting redial and constant dial tone.
Eventually created another account using a different email address, as by the time all this has happened I've already committed myself to going, and cancelled other plans. Should have taken the hint and not bothered as by the time this has all happened I wasn't in the right frame of mind to chat to anyone.
Even on the event, it just seemed like it was disorganised, the woman running it was slow and didn't have much of a clue.
I've since sent them a message on Facebook, but as it's golden week not hearing back for 5 days may just be holiday issues, but hard to tell with these guys.
The first time I went, I had a good night. Last time it felt like a different company running the event, or perhaps their English speaking staff have all disappeared for the holiday season but I'm not sure I'm willing to take the chance with them again.
Kind sucks that while I'm chasing them to get signed up, they are short of men and phoning around to offer places for free!
