There's a new post on 7PHP.com talking about a new giveaway they're doing in collaboration with the Nomad PHP (virtual) user group and giving away two tickets for the upcoming meeting.

NomadPHP is already on their 3rd edition and I’m hence also on my 3rd Ticket(s) give-away. [...] The topic of this 3rd talk will be centered around PHP and Websockets and will be presented by speaker Corey Ballou.

There's two ways to enter into the contest - either subscribe to their mailing list or Tweet about it (with the given tweet). The contest ends July 21st, so hurry and enter if you're interested. The Nomad PHP user group is "a (virtual) place to call home" if you don't have a user group in your area. It meets online once a month.
