The server can't tell whether you're using TooManyItems. However, you need to be a server operator to use it, as it relies on commands like /give.
TooManyItems should work with any server that allows you to use the /give or /i commands.
You cannot turn into animals in normal vanilla Minecraft. However, many servers have plugins which allow you to disguise as different animals.
Only Server OPS can use mods like Too Many Items.
Only if you are in single player. On most servers, if you try to use commands or too many items it will say that you are not able to use that command. If it does not and you get the items you may be banned from the server for cheating.
There are many, many thousands. You can go on websites such as Planet Minecraft or Minecraft Server List to find some that you would like.
There are not many Beta servers up at the moment, but the ones that are can be found with Google. engamma.dyndns.org
That depends. Many servers have their own ip address. Some servers work on hamachi, which has a totally different type of ip address. Each Minecraft server ip is different, but you can find different servers on any website or make your own with port forwarding or hamachi. For general multiplayer servers just type in 'Minecraft Multiplayer servers' and you should come up with many websites with tons of good servers to try out! Happy Playing! ;)
Yes, too many items is free :)
Too Many Items is one. use: give you any item you want in that version of minecraft although some servers will not let you use this mod or any mods at all.
if you mean a black screen then it means the too many items you downloaded dose not support the version of minecraft you have the 1.9 too many items
yes if they set spawn in the nether, but not many do
You can find it on the Minecraft forums.
I assume you mean allowing the items to show up in Too Many Items. I believe there is some kind of config item in the .minecraft folder.
