Blood 2 HTML is a program that will take a text capture file and color code it. It then turns it into either an HTML file or a file for posting in forums.
The LLT Exp Calculator is another creation by Locke Cole. It accurately determines how much experience a character would need to level. It also has a number of other features like determining about how much mana, HPs, mana regen, and encumberance you would have depending on your level and stats. NOTE: the encumberance calc on this is off. it's still on the old 48 encum. per 1 strength.
