This may just be my own opinion here but if things get out of hand with the swap you could well see a loss of interest especially if people start getting impatient and testy. The swaps can't be easy to do and the person running them has to be ready to do everything that they need to. I for one won't do them if they ever become a race to get to the next one going and done so the next one can begin. These are supposed to be fun and make us work to find new patterns and do something that everyone will like, not manufacturing races.
Let's keep them fun, I know that everyone wants to do another one and if there are a lot of members who feel left out let's do 2 at a time or overlap them but let's not make this a task instead of fun.
I love taking my kids fishing, now if I could just manage to fish at the same time.
