I was never good at introducing myself and the like. *sigh* But, oh well, here goes:
Name and Age: I'm Jake (insert my last name here; ha! as if i'd tell the lot of you) and I'm 18.
Purpose for being here:I was strongly recommended to come hither, and displayeth my worketh, by the ever so wonderful Heaven Sent.
Writing: I'm a writer. Surprising, ain't it? *sarcasm* A writer who joined a writing site to tell fellow writers that he too writes.
Captain Obvious! To be more in the speciffy category, I write stories and plays and such. A poem or sonnet may spring to me every once and a while, but I'm not going to be popping those out frequently, so don't expect it from me but so many times a...well...year. Century even. 
Siblings: I've got two sisters. Both are older than me, which apparently makes me the...*sigh*...baby. -.- Blast. The youngest of the two should be having her first child around September. Woohoo for first time uncles!!
Skills? I'm skilled at being that special neighbor who you meet when you first move into a new neighborhood. You know; the one who borrows your junk and doesn't return it until AFTER it's unrepairably (not a word, i know) broken?
Yeah. That's me!!
Interesting Info: Uhh...I'm white?
Random thing you've discovered whilst being bored: Most of the skin cells on my hand and wrist are triangles.
So...*ahem*...You single?
*breath mint*: 
I really do hope you're a girl or I swear I am OUT of here...
Are you bringing sexy back? Psh!! I took it, I'm bringin it back, and I'm takin' again, sucka!
Anything else? Yes. You're ugly. Now, away with ye!! Hehe.
Ta ta! Hope you enjoyed my random ramble.
Yours,
Jake. Not 'Jack'. JAKE! Don't get it twisted...
