While I am not positive how you have your databases structured, I wouldn't think it terribly hard to list (a simple SELECT would do it I assume) Liquibet points next to the names of a poster.
(I.E. perhaps after # of posts, or as a footer)
Just a thought (not a gripe), as the Liquibet idea is quite entertaining as it is.
