What is GrowRows for?
GrowRows is for when you want to pull a list together with the help of a bunch of generally cooperative people and in spite of a few less-than-cooperative people.
How does it work?
You start a table, and give anyone you want involved a link to it. They edit the table however they like. Their edits stay in a copy of your table until you approve them. Their edits are presented to you in an easy-to-review form.
When should I not use GrowRows?
If you trust everyone involved, or are willing to clean up spam and unintentional errors, you might want to consider ethercalc (or failing that, google docs).
