You can edit it and add your improvements in there directly :)
Just find the ‘edit’ button on a wiki page.

Yes I know we can edit it. But what if someone wants to comment on an article or discuss about it. The way we have in Forum Nokia and Symbian Foundation Wiki.

Hi, we don’t have a “talk” or “discussion” page connected to each wiki page as you have on other wikis. To discuss a wiki page you can however start the discussion in the wiki forum and link to that thread on the wiki page.

That would be a good alternative. However, the owner of the wiki page might not be notified unless he checks the forum.

We will have to see how the wiki/forum linking evolves. Owners of wiki pages can subscribe to their thread or the wiki forum as a whole via RSS.

In order to subscribe to a thread they will have to check if a thread has been created for their contributions. Even if someone subscribes to the whole RSS She\he will have to go through all the posts.
