Church in the Hall - an exercise in flexibility

On Sunday we all found out what the surprise at church would be - we met in the hall! The surprise will not be long lived since it is only a temporary thing. The idea is to be in the hall for another three weeks as a training exercise. The two main goals are:

1. being able to do new things together as a church
2. seeing our church building with new eyes when we go back

I know that there might be lots of positives and negatives about being in the hall, this is really just secondary to the two things above. What did you think of it?
