Was typing this at the same time as the others so going to post anyway

Hey there I have been playing High Elves for over 3 years now and have really enjoyed the army.
I feel the best way to get into an army is pick the models you like best or base it around aspects of the game that you enjoy. No point buying a heap of mages and you really dont like to use magic.
I dont know how much you already know so I am just going to start with the basics.
Your best bet is to pick a points value you are happy to start with. I would suggest at 1000pts as this will allow you to get to grips with the game and not over welm yourself then you can build from there. 500pts is played but not that often. Game sizes tend to be played are 1600pts, 2000pts and 2400pts.
Which models should I use?
This is going to depend on what type of army you are going to run and who you asked that question to.
These are my suggestions that I feel are auto includeds.
Mage- You need atleast 1 you are going to have a real tough time otherwise.
Battle Standard Bearer- Never leave home without one.
Eagle - One of the best 50pts in the game.
Swordmasters, Whitelions or Phoenix guard - Take your pick, the elite infantry are all great choices.
The game these days tends to be about not giving away easy points. Big units, well protected Heroes, and hard to kill units are the way to go. ( There are exceptions ).
Post up a list on the forums. There are alot of guys here that play who I am sure will give you tips and tricks then try to get a game sorted.
