Hi! The old beta post was a bit outdated, so I decided to start a new one.
If you are willing to beta for one of the authors in our challenges, please post here.
If you are looking for a beta, please keep checking here to see who has offered, and if you see someone you'd like to ask, please reply to their comment or contact them however they've indicated works best for them.
There is also a "Beta Central" post on our mirror community on LiveJournal if you want to check there for a beta as well.
Thanks so much to all the wonderful betas out there!
