We are a not-for-profit organisation and are very appreciative, grateful and thankful to http://highslide.com for their generous licensing policy of allowing not-for-profit organisations to use their wonderful product without charging a fee.
Those who grumble at the little thing that has fallen to their lot to do will grumble at everything. Always grumbling, they will lead a miserable life, and everything will be a failure. But those who do their duties as they go, putting their shoulders to the wheel, will see the light, and higher duties will fall to their share.
