As this doesn’t contain wp-admin, uploaded wp-admin from the 2.0 install package

It should, and just checked the 2.0.1.zip and it is there. Is probably a good idea to download all the files again first.

A couple of thoughts:
1. Dump the WYSIWYG editor if you have not already (bottom left on your user page), in favour of the quicktags.
2. Track down and install the Text Control plugin. Works for me on 2.0.1 and has a selection of options, one of which might do what you want.

for one thing, upgrade it to 1.5.2. then to version 2.0.1

Both 1.5.2 and 2.0.1 have no known security holes, the 2.0.1 upgrade is optional if you want the features (and 2.0 only plugins).

Try following the suggestions in this thread. It is ‘number’x ‘number’ that WP is reformatting:

Searching pages can be done via a plugin:

Not sure about searching links though, maybe there is a way to implement google to do that.

I think there is/was one at redalt though if you want to search further ‘AJAX comments‘ is probably a good starting point (or there is disecting the K2 theme to see how it works).

You will need to use an FTP program. Podz has a handy guide to using one here..

This is not completely tested but I think it should work, make sure you backup first….
Above the line the starts the loop <?php if (have_posts()) : while [...]
paste this:
<?php $adcount=1; ?>

Then, within the loop add this where you want your adverts to appear:
<?php if($adcount%2) { ?>
<div class="your ad div">
Your ad code here
</div>
<?php } ?>
<?php $adcount++; ?>

Hopefully that will put ads on posts 1, 3, 5 etc.. to put them on 2, 4, 6 etc use
<?php if(!($adcount%2)) { ?>
instead.

To limit the number of posts that show adds I would think the code would be
<?php if(($adcount%2) && ($adcount<=6)) { ?>
where 6 is twice the number of ads that would appear (untested).
