<p>Create your own category-controlled ‘Top Tip’ to display next to relavant posts.<br />
Display you favourite top tip next to a post with the same category. If you have more than one tip in the matching category the chosen top tip will be a random selection from all within that category. It’s also possible to specify the top tip by id in a shortcode. An optional feature is to add a link to another post containing further information about your Top Tip.</p>

<li>Create some new top tips and assign them to one or more categories.</li>
<li>Add the shortcode [top-tips] to your posts or in a template file <code><?php echo do_shortcode('[top-tips]'); ?></code>.</li>

<p>This plugin inserts a TipMe icon in WordPress posts if the user has a Twitter username and has put the Twitter link in their website field of their profile.<br />
TipMe buttons for BBPress posts are inserted so users can get tips if they just have a<br />
Twitter link defined in the website field of their profile.</p>
<p>In short, it creates a tweet that the ChangeTip bot pics up and delivers with just one click.</p>
<p>We are using it on some of our web sites, so thought others might enjoy using it on theirs, but it comes without any warranty express or implied, and should be used at your own risk. It is a quite simple concept so should be quite reliable.</p>
<p>This probably will work with earlier versions of WordPress, but has not been tested.</p>


TipMeWP
