I've been around here & there, L. I've just reordered my priorities a little to allow me more time to spend on my (bonsai) trees and in my own gardens, which means I don't get here as much (usually too tired by day's end). ;-)
When you called yesterday, I was on a road trip in southern MI, visiting nurseries with a dear friend of many years who is visiting the US after having abandoned me when she moved back to Sweden. I didn't recognize your number or I would have answered. It was only after I got home & checked the area code that I realized who it MUST be. ;-) Got your D-mail too. It's easier to answer your questions by phone, but if I don't here from you, I'll reply via D-mail. Skip the manure, though. It doesn't offer anything you can't get from fertilizer (except maybe weed seeds), and if (excess) water retention was previously an issue, the manure will almost certainly exacerbate it.
P.S. Out of desperation, I went back to Gardenweb and started reading the threads from part IV. I found a post where someone wanted to reuse your 511 mix a second season, and I zeroed in on your reply. I think I know which direction the old mix will be headed. Although, I was hoping not to have to sift through new PBFs. But, hey, the mix worked wonderfully well, so, I'll get on it this weekend. My seedlings are about ready to jump on a plate and be eaten!!!!
Too bad you don't live closer. Love to have you over for a home-cooked meal of mustard greens & rice, smoked turkey necks, fried chicken, and candied sweet potatoes. Louisiana Red Hot Sauce on the side. Still deciding on dessert!
