MultiNetwork Blog support

I updated to wordpress 3.5.1 few hours ago
I have a problem now
in my website there are three blogs in three sub-domains by using multinetwork

> news.domain.com
> announcements.domain.com
> ece.domain.com

On my home page i want to get the feeds of all this like

<table>
<thead>
<tr>
<th>Date & Time</th><th>         Title  </th>        <th>           Author   </th> <th>  no. comments</th>
</tr>
</thead>
<tbody>
<tr>
<td>10min ago</td>
<td>You have logged in wordpress</td>
<td>author name</td>
<td>3</td>
</tr>
<tr>
<td>5min ago</td>
<td>Hello, welcome to wordpress</td>
<td>author name</td>
<td>2</td>
</tr>
</tbody>
</table>
