A few questions about this wiki and wiki's in general.
'''How open/closed is wikieducator? ''' I think using wikispaces you can only edit if invited. Can others even find the space using a search? Is it the same for all wiki areas? Which is the best one to use with undergraduate students?

Wouldn't it be great if there was a spell check.

Is this the best way to get a more professional look? What is the difference between a rich editor and other editors?

Here's my project:

What else should I add? How much should I let the students do if the resources is meant to be one for them and by them?
