First things first. I tried to keep this private, not spam up the forums with this, but Lex has PM's off. LexManos and many other people here need to get off their high horses and stop trying to force everyone to use the latest version of Minecraft. Many people, myself included, use 1.5.2 and older versions because there are mods that are not updated to work with the latest version of Minecraft. Some examples:
LexManos himself.
Not LexManos, but someone else saying the same thing.
Seriously guys? Feed the Beast and Tekkit are only just now updating to 1.5.2 because the mods are finally stable across the board. Don't start telling people to stop using older versions just because there's a newer version.
