the first phase of beta is usually done by the programmers and admins. Then members of rulesteam might test it along with concerned factions. Like leaders of production factions. On occasion there is an "open" beta.
Right now the only thing I need is more time. In a few days 'll be needing math whizz's to work on the equations. If I come across any production work that needs doing that doesn't require dev access 'll let you know. Cheers for the offer.
