Here is a direct link to the forums for the site. Oftentimes people ninja as guests on the forums before actually joining, so try that out if you're skeptical.
Metal Machine Music is a Zoids RPG site which offers both a great chance to RP, but also a chance to partake in the fun that is Zoids battling. You can have/be in as many RPs as you want at one time, in as many different points of your character's life as you want.
But many people will tell you the real bread and butter of MMM is the Zoids battling. Even if you're unsure of joining, I encourage you to try out the unofficial battling, which can be done by pretty much anybody visiting the site, without your character being approved or anything.
Unofficial and official battling happens over instant messaging, while official battling is also conducted on the forums for those who don't have a lot of time on their hands to sit at the computer for a battle over IM. In the on-forum battles, you have 3 days to post your round of action in combat, which is plenty of time to plan and get your move posted.
MMM has a great staff, a hilarious community, and it has been around for many years already. It is a site looking for more members who are committed to having a lot of fun and beating the crap out of each other with Zoids.
A direct link to the Character Application's page can be found here. It has a concise description of all the steps you should take, as well as links to every bit of pertinent information. And before there is any "Wtf, I have to apply to play on this site?!?" I'd like to explain. It is just so the admins can keep tabs on the characters, and not let in anybody who wants to godmode, who has a character that just doesn't fit the setting, and all the brainless 12 year olds prowling the internet. In all honesty, the application thing takes no time at all, and you can get loads of feedback by asking for help on the forums.
Oh, and if you do check it out and apply, then put down "Oskar Dunwair" under the referral part of the application. Thats my name on MMM.
