Ok hopefully every one has installed evemon by now.
Under tool you have the option "Synchronize with inEVE.net" use this option it will take you to the inEve website and ask you to sign up. After signing up to inEVE you can log in and compare your skills with the rest of the members in our corp. So we can easily help you by giving accurate advice on what skills to train and what skills is not needed. We can also help you make decisions on what ship you could get based on your skills...
For example if a new member signed up and said he wanted to do PVP we could check his skills and for example see that he has good missile skills we then look at his spaceship command skills and would recommend him a good missile ship that he would be able to fly.
Also by being able to see what skills we already have in our corp we will be able to identify out strong points and weak points we could then set out campaigns to hire players strong in the skills where corp falls short in the long run making the corp stronger over all and thus better for all players.
NONE of this is compulsory it just makes making decisions easier and also helps plan for the long run.
