Reputation Box in Showthread

[Lynne]

There are a few reputation mods here. Have you checked them out to see if any of them do what you want (search "reputation*" in "all mods" "titles only")?

It's hard to say whether you can do it with just template edits. If you know the variable names and they exist without a database call, then sure you can do it. If you need a database call to get the information, then you will need to write a plugin also.
