Simple Recipe Addon: need help with publishing

My mod works perfectly inside the MCP environment.

From what i can tell this is how you publish a mod:
1. In MCP use Recompile - when i do this says cannot find server sources, but i just press on
2. In MCP use Re-obfuscate - run this, everything works, get a message: Can Not find server md5s, but i just press on.
3. Look In "reobf" folder for re-obfuscated files. - yepp, they're there.
4. Find your Mod, in my case i called it "DDP_IC2RecipeAddon" and put that folder in a .rar - okay!
5. drop that .rar in mods folder, and there ya go. - i do this, and minecraft doesn't even seem to think my mod exists, as if i never dropped it in.

What am I doing wrong? I know this might seem like a stupidly easy thing for you guys, but i've never published a mod before, so I could play with it.

It's funny, about 5 minutes after i posted this, i realized that, after going through other mods and looking for any obvious differences.

Thank you for your help though!

now i just have to figure out how to get my mcmod.info file to actually work.

Not that it matters too too much: my mod works, that's what does matter.
