By default, vBulletin 5 only displays the Join Date and Post count in the postbit area (avatar and username section) in the thread view of a topic. There may be other tutorials out there to add custom fields in postbit but some require you to edit the existing postbit template. Editing existing templates is not good for maintenance reasons as you would have to resolve template merge conflicts every time you upgrade. Or some might require you to create a template hook and repeatedly copy/paste template code for adding multiple fields and change instances of profile field variable names. Another maintenance nightmare. :eek:

Don't look any further, here's the mod that is simple but rocks! Simply download the zip file, uncompress it and upload the XML in AdminCP > Products & Hooks > Manage Products > [Add/Import Product] and you're good to go. By default, it adds Location and Occupation profile fields in Postbit. You can configure what profile fields to add in AdminCP > Settings > Options > Custom Profile Fields in Postbit Settings.

As a bonus, the mod also adds "Send PM" link to the postbit to make it easier for users to send a private message to a user while reading a thread. You can also configure that in the Custom Profile Fields in Postbit Settings.

Compatibility: vB 5.x.x
