Help me! So I like this guy...?

I've seen this guy around basically since middle school, he's a grade under me, but the same age...
Towards the end of May I went to a party in which he attended... we basically knew who eachother was & had a class in middle school (but barely spoke).. saw eachother around, but we don't exactly know eachother... we got drunk, and kissed, and fell asleep sitting next to eachother on a bench in the backyard...
about a month and half later, I'm still thinking about him! I just recently got a myspace and added him, and he added me back, so he knows who I am, but he has no idea how much I like him!
I don't want to message him or anything, because really we don't know eachother, and I don't want to be so forward because I feel like he doesn't remember... but what if he does, and feels the same way towards me?
How should I get him to talk to me?
What should I do to call attention in subtle ways?!...(only on myspace, because there is no way of me seeing him in person, unless its random)

There's nothing wrong with sending him a quick myspace message, especially if you don't see him in person. That way, if it turns out to be embarrassing that you messaged him, it won't really matter.

Just ask him if he remembers what happened at the party.. and go from there. If he says something like "yeah I remember it was fun" then invite him to go hang out somewhere. Concert...pool...movie...lunch...etc.

If u like him then you have to message him cuz there isnt any other way just talk to him like normal and ask him if he remembers the party u attended and tell him how fun it was or soemthing and tell him what happend and stuff he will probably remember so good luck!
