Adventures in Blog Creation Exploration

I've been at this for hours. I actually spent nearly an hour on another site creating a free blog only to discover after choosing the background, layout, font, title, the works that the first 31 days are free and then it's $20 for 3 month's subscription, or else it will all be deleted. I deleted that and explored a few profiles on Ravelry that linked here to their blogs. I hope I don't have an expiry date here - doesn't look like it.

It's been a fly by the seat of my pants learning experience for me this evening. I'm unfamiliar with the words on the links and all the vocabulary around this activity. Clicking on things in hopes of deciphering it's meaning and ending up entirely elsewhere from where I think I need to be - other windows opening; and then the 'back to' option landing me up with more than one window with the same thing in for my many attempts to get back to point A and figure it out from there. Still not certain what point A is quite yet.

I am off to see if I can figure out how to add my Blog ULR to my profile on Ravelry.com: CastOnCalamity although I may have to wait and consult my teenager-type peoples who are home for the summer from college. Onward with this adventure. Also, and most importantly: I would like to know if I can make a pdf or two or three available for downloading on my blog somewhere.
