Hi

1. People (like myself) will pollute the Debugging Page, or such, with badly edited and erroneous `draft' ideas, and then, who would like to read this page?

The great thing is that people with knowledge can put their knowledge up, and people with a coherent use of English and some editing skill can refine it.

2. I edited this Page by adding my message. And what if some user removes all messages, editing the Page to empty?

We go kill that user :) - there is a Page History, if some user does nasty things, we can revert back to before then. The Yhc manual is entirely on the wiki, and its worked out great. The Hoogle manual is also on the wiki - I wrote about 25% of it, and other helpful people fleshed out the rest - its a great way for the community to work together to get excellent results. Thanks Neil
