[Ore Dictionary?]

Not just for 'ores', it can be used to provide mapping of any identical 'basic' items between any mods should they choose to use it.

[[CODING] Stairs? - How?]

Minecraft itself will throw an exception if 2 blocks have the same ID.  Forge does not change that at all as it is quite effective.  You can blame Eclipse for catching the exception.

[How do I reintroduce a block in my mod class?]

For note, that will only work in MCP, not as an actual mod.

[Dragon-Proof Block Hook]

Would be appreciated. 

[blockActivated hook]

Forge is undergoing massive additions lately, it will be gotten to soon. 

[AchievementPage BG customization]

Not a bad thought, IC2 could use it as well...

[[world generation compatibility] Idea for classifying world generation pieces]

Might want to speak to xcompwiz about that as he is making very useful and sweeping additions about things in this area.

[Change to the "Mods" folder]

A mod that does base edits, regardless of how it bootstraps itself, is not an ML mod.

[Dragon-Proof Block Hook]

Hmm, this is not a bad idea...  Can someone do a PR for it?

[Block with Textures from 2 Terrain Sprites]

See how fire/water textureFX's work?

[How do I reintroduce a block in my mod class?]

Java Reflection

Google that.

[Where to store player specific data accessible by items]

When key is pressed, look at player and see what their active item is, if yours then do what you need.

[How to I manually start minecraft using 'Run'?]

Or just look in the ForgeModLoader-?.log file.

[Duplicate method name&signature error]

Probably the storage minecart is the traditional way?

[draw to HUD, before GuiScreen]

I am not sure, but if you can find a good injection point then you can submit a Pull Request. 

[Custom Fire Colour]

TextureFX, will need to learn it.

["Repopulate" already generated Chunks]

You can corrupt the chunks that you want to regenerate using the map editing utility.  When MC reloads it then it will regenerate.  Make backups of course!

[Decompiling]

Ok i think i figured it out.

 

with the newer forge version you have to download the source it comes with a installer type thing that you put in the mcp directory and run.

Yes, and all that is in the readme. 

[Add a new stat to EntityLiving using ASM]

Near the end of the variable declarations on Entity or EntityLiving or whatever it was there is a commented variable saying that it was added by Forge for just those purposes.  You can read from and write to it just like an normal NBT data. 

[Need help understanding MP TileEntities, Update Packets and all that stuff]

I would recommend looking at cpw's IronChests and CompactSolars mods as examples:  https://github.com/cpw

 

In essence though:

 

GUI:  You have a container on the server side, a GUI on the client side, they talk, plenty of examples in vanilla as to how, but usually it just works.

 

TileEntities:  You use the getDescriptionPacket call or whatever it was to send information to a TileEntity, you want to minimize the size and how often these occur, 'emulate' things on the client if possible, the lower network usage then the better. 

[[Solved] Can't decompile Forge for the life of me]

Yeah, that is an MCP'ism.

[Add a new stat to EntityLiving using ASM]

You can attach arbitrary NBT data to any entity, why would that not work for you?

[Forge Events]

Cannot really help without the log of the crash?

[How to disable specific mods with Forge]

I do not think so as of yet, but I think it is on the roadmap.

[Is the "not working with external launcher" problem getting fixed??]

MultiMC ( http://forkk.net/MultiMC4/ ) works fine and is superior.
