Mobile Posting

I'm posting using mobile o: was reading about posting using sms, but after read and reread still have no idea the gibberish they are talking in the direction. How the heck to post using sms/text w/out having a new blog. I've got more than I can chew tyvm w/out adding more blog to maintain. help, please, anyone?

update: ahhhh, got it how to post on blog using SMS, but meh.. it'll cost more than just to go online and post, consider how many characters needed to type this post times the cost of texting.. online FTW
