You could always use the profile field manager. By doing the following
- Create a single line text profile field.
For example i made one called processor. Typed in my description for it and clicked save.
- Make a new phrase in the phrase manager. for varname I put processor_type and for the text I put processor
- Then I edited my postbit_legacy template to include that profile field. You can see the code in the attached image
By doing this is shows up in there profile and postbit. The post bit is the part that displays the users pic username and other stats when posting a thread or topic. Then your users can input there info from the userCP under edit profile. see images
