I'm looking to set up a masternode and thought it would be a good idea to anonymise the coins before locking them up indefintiely. I went for 8 rounds - if something's worth doing, it's worth doing properly, right? I've had my client open for the best part of two days waiting and so far it's 12% complete (1 round). I did close the client for a couple of hours at one stage and then again for a little while more while I updated to the latest version. I suppose it's because there is nobody else mixing similar amounts at the moment but I'm beginning to think there's something I haven't done right. On a side note, I think it would be great for Darksend to have it's own sub forum, and a sticky in the forum about how to use Darksend which can be updated if there are ever any changes to the procedure would be even better.
