PartakeInDiscussion
If you want to comment on something on a page, but you don't want simply to change the page (which, of course, you can do!), then put a line, indicated with four hyphens in a row, like this: ----
and add your remarks below the line, at the bottom of the page. This, anyway, is a nice convention to follow. In principle, there's nothing stopping you from adding your remarks anywhere.----
Click "Edit text of this page" below to see how this was done...the four hyphens will be revealed.----
Perhaps an even better idea is to create a *Talk page (such as ElephantTalk, which is comment on the ElephanT article) and move the discussion there. After all, we'd like to focus on encyclopedia articles.----
By the way, you can participate on WikipediaL if you want to discuss something that, for whatever reason, you don't want to discuss on Wikipedia itself.
