Some people like recording the Experience Nodelet on their homenode when they find a particular one to be significant or amusing. When i hit Level 13: Curate someone kindly sent me the following code (which i modified to meet my needs):

<table class="nodelet_container" width="300">
 <tbody class="nodelet">
  <tr class="nodelet_head_row">
   <th class="nodehead" align="left">XP Nodelet</th>
  </tr>
  <tr class="nodelet_body_row">
   <td class="nodebody">
    You gained 2 experience points. I've got a million of them.
    <br>Your new level imbues you with super-powers! Check out [id://5
+04005] for the details!
    <br>You have 999 points until level 14 - Priest.
   </td>
  </tr>
 </tbody>
</table>
[download]

This shows up as:

XP Nodelet
You gained 2 experience points. I've got a million of them. Your new level imbues you with super-powers! Check out Level 13: Curate for the details! You have 999 points until level 14 - Priest.

The text itself needs to be copied from the experience nodelet. It'll wrap itself, but add <br> for new lines. If you already closed the browser tab with the text, chances are you can pull it back up from history or go back to it as necessary.

Though the experience nodelet does not use it, you can show a caption with the <caption></caption>tags inside the table.

Update: Added align="left" in <th> because "XP Nodelet" should not be centered.
