In fact- never mind. There's only one Forge-compatible mod out ATM on Planet Minecraft that I can see- all other mods are actually Bukkit plugins. Unfortunately, due to several reasons, Forge and Bukkit mods don't play nice without a special environment, such as ForgeEssentials(?) and BukkitForge. As far as I know, neither of these have taken the leap to 1.7.2. Yet. Long story short- use Forge mods with Forge, and Bukkit with Bukkit mods. At least for now.

Hmm... could you name the mods you're trying to get to work?

It may be slow, but most of the names can be "guessed" from previous releases. Compare the 'vanilla' codes for most blocks and items in 1.6.4 with the current 1.7.2 code, and most of the time, you can take an educated guess as to what they do. The vast majority of code changes that I've encountered seem to be surrounding the loss of Block ID- but then I'm only making a simple mod! If you do use this to update your code, make sure to make a note of what the original code was, as you'll probably have to change it back anyway in future versions.
