One of the Toledo reef clubs does that too (traccentral.org) but we are too small to get much going at any one time. We extended it to just about anything aquarium related,
have an old pump that works but maybe a little long in the tooth pass it on when someone is in an emergency need.
Its a great way for less experienced keepers to meet those with some success behind them. (I didn't want to say old LOL)
Here is my thoughts for this site's pay it forward if we are so inclinded (works better if you are local but the mail can be fine too)
The here is a frag of a great starter zoa, keep it like this , with those lights ect. when you get more than a few polyps let me know and I will show you how to frag it and pass it on to someone else. Down the road the newbie and their mentor can trade back and forth to balance each others collections etc. Life long pals from a simple act of kindness

Oh and is it too late to get that free frag ???
