Welcome aboard! Thank you for asking questions before diving in. The BattleMech articles, in particular, have a lot of guidelines surrounding them because everybody has a different idea about how they should be organized. The great thing about a wiki is that you can just dive in, but sometimes it's a good idea to figure out how deep the pool is first.
I encourage you to write a little bit at the new user log to introduce yourself. If you're interested in 'Mech articles, you should consider signing up for WikiProject BattleMechs. See you around! --Scaletail 22:50, 5 August 2011 (UTC)
