So I have multiple pending transactions in Electrum that have been sitting with zero confirmations for four days now. I've had other transactions go through since then, but on these I apparently didn't use enough of a transaction fee. On another site, someone suggested I try "child pays for parent" and pointed me to https://bitcointalk.org/index.php?topic=729535.msg8251404#msg8251404. Now, I'm a total newbie, just started with bitcoin like a week ago. I sorta understand the concept being described in that post, but I'm not sure I follow the process. It's just vague enough to be confusing to someone who doesn't know what they're doing. For example, right away in step 1, it refers to a different transaction than the one the OP of that thread originally asked about. What's the connection there, and why does it come into play later as well in step 3 where there are now three transactions involved? And in step 2, do I have to send it back to the original sending address, or literally just any other address?

The person referring me here didn't know enough to help me further, so I thought I'd come to the source. Basically, it would be amazing if someone could give me an idiot proof blow-by-blow of the process. Maybe I could follow it better using using one of my pending transactions as an example, like this one: https://blockchain.info/tx/d98144e300e6a119ed54a47df73c3ead075d00f1fb2417f952c4dcd4ad6752fe
