Chuckroast brings up a good point. Pligg wouldn't know what to set the page titles to, which would kill your search engine results.
I haven't tested out the code below, but I suspect that it should work.
Find this in submit_step_2.tpl:
Code:
<label>{#PLIGG_Visual_Submit2_Title#}: </label>{#PLIGG_Visual_Submit2_TitleInstruct#}<br/>
<input type="text" id="title" class="text" name="title" value="{if $submit_title}{$submit_title}{else}{$submit_url_title}{/if}" size="60" maxlength="{$maxTitleLength}" /> Replace it with this:
Code:
<div style="display:none;"><label>{#PLIGG_Visual_Submit2_Title#}: </label>{#PLIGG_Visual_Submit2_TitleInstruct#}<br/>
<input type="text" id="title" class="text" name="title" value="{$submit_id}" size="60" maxlength="{$maxTitleLength}" /></div> That will hide the story title input field when submitting the story. You will need to then go in to link_summary.tpl and remove these lines to get rid of the title display:
Code:
<h2>
{checkActionsTpl location="tpl_pligg_story_title_start"}
{if $use_title_as_link eq true}
{if $url_short neq "http://" && $url_short neq "://"}
<a href="{$url}" {if $open_in_new_window eq true} target="_blank"{/if} {if $story_status neq "published"}rel="nofollow"{/if}>{$title_short}</a>
{else}
<a href="{$story_url}" {if $open_in_new_window eq true} target="_blank"{/if}>{$title_short}</a>
{/if}
{else}
{if $pagename eq "story" && $url_short neq "http://" && $url_short neq "://"}
<a href="{$url}" {if $open_in_new_window eq true} target="_blank"{/if} {if $story_status neq "published"}rel="nofollow"{/if}>{$title_short}</a>
{else}
<a href="{$story_url}">{$title_short}</a>
{/if}
{/if}
{checkActionsTpl location="tpl_pligg_story_title_end"}
</h2> That's it for the basics. There are probably some other areas that will still show the title (ex. the Live page), but you will have to find all of those smaller examples and correct them on your own.
