        <h3>PostMe</h3>
        <ul>
        <p> FHEM module to set up a system of sticky notes, similar to Post-Its&trade;</p>

        <a name="PostMedefine"></a>
        <h4>Define</h4>
        <p>
            <code>define &lt;postit&gt; PostMe</code>
            <br />Defines the PostMe system, &lt;postit&gt; is an arbitrary name for the system. </p>
        <a name="PostMeusage"></a>
        <h4>Usage</h4>
        See <a href="http://www.fhemwiki.de/wiki/Modul_PostMe">German Wiki page</a>
        <br/>
        An arbitrary number of lists may be added to the system with the <i>create</i> command.<br/>
        List items may consist of one or more words, and are added/removed by the <i>add</i> and 
        <i>remove</i>  command, but no separator characters are allowed in one item<br/> 
        Attention: A comma "," is the <i>default</i> separator for list items, see attributes below.</br/>
        <p/>
        Meta data for items (=annotations)may be included in the items by using "[" and "]"; characters, e.g.<br/>
        <code>set &lt;postit&gt; add &lt;name&gt; &lt;item&gt; [&lt;attribute1&gt;="&lt;data1&gt;" ...</code><br/>
        These attribute-value pairs may be added, modified and removed with the <i>modify</i> command. 
        <p/>
        <b>Special annotations</b> will be evaluated further, either on creation or manually by executing the commands<br/>
        <code>get &lt;postit&gt; special &lt;name&gt;</code> resp. <code>get &lt;postit&gt; allspecial</code>
        <ul>
          <li>The attribute <i>at="&lt;timespec/datespec&gt;"</i>, when given a timespec/datespec value, will result in a single or multiple
          reminding messages for this item. The syntax for this timespec/datespec value is<br/>
          <code>(&lt;HH:MM&gt;|&lt;HH:MM:SS&gt;|&lt;YYYY-MM-DD&gt;T&lt;HH:MM:SS&gt;)[-&lt;HH:MM&gt;[P&lt;number&gt;]]</code>
          <br/>
          The first part is the time/date specification when the item is <i>due</i>. 
          <br/>The second optional part beginning with a "-"-sign
          denotes how much time befor this date you want to be alerted. 
          <br/>The third optional part beginning with a "P" character 
          allows to specify a &lt;number&gt; of periodic reminders, the period given by the second part.<br/>
          Processing this attribute means, that several <i>at</i> devices will be set up in the room <i>hidden</i> 
          that are triggered when at the specified times.
          See documentation in Wiki for examples.
       </li>
          <li>The attribute <i>notify="&lt;eventspec&gt;"</i>, when given an eventspec value, will result in a single or multiple
          reminding messages for this item.<br/>
          Processing this attribute means, that a <i>notify</i> device will be set up in the room <i>hidden</i> 
          that is triggered when the event is detected.</li> 
        </ul>
        The sticky notes may be integrated into any Web page by simply embedding the following tags
           <ul>
           <li> <code>&lt;embed src="/fhem/PostMe_widget?type=pins&amp;postit=&lt;postit&gt;"/&gt;</code> <br/>
