taking your example, if i write {{Computer page}} in
any place of my page(lets say start or middle),
will my text appear at the bottom of my page? I've already tried this, and it appear
always at the beggining.
By default, the text will appear exactly where the template appears.
You can place the text anywhere you want using CSS. Just enclose the text in a div:
<includeonly>[[Category:Computers]]</includeonly><div
class="computer-info">
This is a wonderful wiki article about computers.
</div>
and then edit MediaWiki:Common.css to add a class ("computer-info ") that places
the div at
the top of the page.
div. computer-info {
...whatever CSS you want...
}
