I have two questions with frames.. the first is, how do you make an inline frame that is centered on the page both vertically and horiztonally? Also, is there a way to make a link in one from open new pages in more than one other frame? Thanks.

You could use a table to centre the iframe:
<table width="100%" height="100%">
<tr>
<td align="center">
<iframe></iframe>
</td>
</tr>
</table>
