Typing in capitals is considered to be the same as shouting, and therefore very rude. Asking potential helpers for "a fricken reply" is also likely to reduce your chances of getting help.
Now, before anyone can help you, you can start by explaining exactly what is or isn't happening in your game rather than saying "they don't work".
By that do you mean:
- Other people can't see your skin?
- You can't see other team member's skin?
- You can't select them in game?
- They don't download from LFS World?
- They won't upload to LFS World?
More information, and a friendly manner, will serve you well.
