Yes I think the WU drought was just a temporary situation, currently over 50,000 WU ready to send according to the server status. Validation is getting a bit better for me now, I'm at 125 pending, 58 valid, work units for this project need two other donors to validate that along with the long deadline make these work unit slower than usual to validate.
As far as the challenge goes we're 9th, which has been that way from the beginning, hopefully that will change when we get some momentum going.
Hmm anything in particular? I was hoping your were just after the ruby badge in collatz and that's all
