xPinkpegasusx - I enjoy reading her posts, even if I don't agree with all of them it's refreshing to read some well thought out opinions on the housemates/BB.
Shaun - Presence in the BB section, unbias opinions and effort of running the TiBB Noms every time BB is on.
Nimah - I don't even like her but enjoy reading her opinions

the effort she puts in moderating the forum and keeping the place alive during quieter days deserves a mention too.
There's lots I wanted to vote for but there's always next week.
