"...the excellent service I have always received from Freeola."
I do know some people using very expensive domain hosting who do not get a service any where near as good as I receive, I would just like to say that the service is appreciated, and I don't have a clue how you can provide such a service for free.
I feel that your service on this occasion was absolutely first class - a model of excellence. After this, I hope to stay with Freeola for a long time!
