UPDATE 5/23:
YES I still want new testers, and no you are not too late. If you are reading this sometime in June, no you are not too late. Welcome in!
Okay. So the blueshirts are in, and a lot of time has passed since the beta has started, and it's time to start doing things differently. I'm bringing in a new wave of testers every Friday or Monday come hell or high water. In other words, I will try for Friday so that you have the weekend to test, but if things go awry then I will push back to the Monday night after.
On average, at the moment I will be looking for 11 folks per week, although I could probably go as high as 20 for the next while in particular. As of the time of this writing we have 83 people on the list to be testers who have not yet been sent keys, and 48 people who have. We're looking at an early July release, and new folks are still signing up for testing all the time (and VERY welcome to do so in this very thread), so weekly waves are pretty well unavoidable if I still want to have people in waves (which I do want) and not have a bunch of people who volunteered miss out on the beta (which I don't want). We certainly can use every pair of eyes we can get, and every configuration of computer, and every style of thinking, every mix of past gaming experience, and so on.
If we wind up with too many volunteers for a given week, then I'll either pick randomly from that list and then roll the extras over to the next week, or else I'll just do a larger wave that week, at my discretion based on what I think is best for the game based on its current state. Nothing personal either direction on that, and if you get pushed back one week I'll make extra sure you are in the next week.
If for some reason you have specific scheduling constraints and you need to be in this week (or sooner even) if you're to take part, then just let me know (you can PM me to make sure I don't miss it) and I'll get you in sooner. I'd rather have folks like that outside of a normal wave than miss their input all together.
Right now there is a signup thread for anyone who wants to be a yellowshirt, which is what I'm calling the folks coming in next week. But if you are signing up fresh in this thread, you can also just mention that you'd like to be a yellowshirt, or in whatever particular week if you know offhand.
Thanks everybody!
