Q: Where did such and such mod go? it used to be here?
A: If you cannot find a mod that used to be here it's probably been deleted due to lack interest in the project. If you wish to download it again you can try searching the Minecraft Forums for it.
Q: Can I use one of your mods in a modpack?
A: Please read the Modpack Policies page
Q: I can't find an old version of a mod. Can you send me a link please?
A: No, if you cannot find a older version of the mod under the previous versions of the mod, chances are I do not have it either.
Q: Can you make this mod in for a previous version?
A: No, porting a mod to a previous version of Minecraft is more difficult then porting it forward. Especially between 1.7 and 1.6.
Q: What do your version numbers mean?
A: Take for example the version 18.104.22.168
