1. Create an Add-on (for example with productid glossar)
2. Create a phrase blocktype_{blocktypename} (blocktype_glossarentries for example) in phrase group Forum Blocks
3. Create the class in includes/block and make sure that
   • The filename equals the blocktypename (eg. if your class is vB_Block_Glossarentries the filename must be glossarentries.php)
   • You are setting the productid correctly
     
     PHP Code:

     protected $productid = 'glossar'; 

4. Reload the block types by accessing admincp/block.php?do=reload

That's it
