Already have it and use it for BIAB. Started with Qbrew but now couldn't do without Beersmith anymore. Agree that it does need quite a bit of tweaking, but once you get it right, it is pretty consistent.

Finally gave up on the Mr. B site.. Can't stay logged in, not much works like the old site, and I have moved on from Mr. B anyway.
Thankful for Mr. B getting me started but have moved to all grain BIAB almost a year ago.
Hope they get the site working eventually but think I will enjoy it here.
