I think rewriting all the raws, just to make them more orderly, is not quite that important. It might be nice for modders, but then again, modders can do it themselves, sort them into a file-system that they personally desire most. I know for example that deon has done this. I dont think it is very important for the unmodded game, since redoing all the raws is only a source of possible bugs, but gives no more accessability or features for the modders.
The child boards I do like. Mod Releases is great, Utilities would be great, Graphic Sets, and of course I will not complain about the MasterworkDF childboard.
I dont want to step on anyones toes, but seeing how putnams/deons child boards all have one post about each mod in them, I could see them merged with Mod Releases. Granted, they are very new and people did not have much chance to post, so I could be wrong about it. If there is a lot of discussion I can understand a seperate board, but if they are just mod-release posts, people looking for general mods in the mod release section would overlook them. Seriously guys, no disrespect meant.
A pinned first thread in each section, similar to Profits current list, would be very helpful as well. Akin to an index for each child board.
