I am not active right now in this swap but I have been. I encountered the problem of only giving and not getting a block back about half the time. I believe that it is better now. It is my firm conviction that if someone does not fulfill their obligation for one month they should not be allowed to participate the next month. There are some fabulous people in this swap and it ruins it for everyone if all do not do what they are suppose to do. Life happens and being held out a month is not disaster and one can regroup, catch up, and start again. Of course this is IMHO.
