I don't really think so, if you want invite I can give you. The real problem is that many are not able to pass first step of validation, really hard to find serious people who don't miss validation round.
Well, I don't need invites, I also want to give mine away to any newbie joining the project/network but it seems that no one is interested anymore since there are a lot of people who have invite nowadays, some even 2 (humans) + the invites issued by the team.
I'm glad that selling invite is not existing here anymore it keeps the community clean, with so many people getting validated there are more invites to give for beginners, I still believe that IDENA has a good potential in the industry a year from now it will cover a lot,many developers will come in to contribute to this project.
