What is the Blogging from A to Z challenge and where can I find more participants? Right here.

Double check your Timeline. We all like to think we know our story backwards and forwards. The problem is, the odds that we sat down and wrote the whole story in one day are pretty slim. If you're like me, you get interrupted by pretty much everything - the dogs, the kids, the husband, phone, unexpected visitors, work, the repair person...
Not only is it easy to forget what time of day it is in a scene that might span a couple days of writing, but somewhere between the beginning and the end, it's entirely possible that either two previously unrelated characters are doing something that doesn't line up later on when they come together or a secondary character is left stranded somewhere in time. The backstory of main characters might be off kilter with character developing scenes happening later. Did she run away at eight years old, but later on, she turns up on the street at twelve?
The easiest way to avoid this is to plot everything out and stick exactly to your plan. Not one of those people? Yeah, me either.
The rest of us may want to take some notes as we go along in our edits, jotting down ages and dates of important events or when those things are mentioned in the story and actually create a literal timeline to make sure everything corresponds.
You might think an editor will do this for you, and if they're super awesome, they might. However, your best bet, is to make sure your story is correct and possible before sending it off so you know it's right. After all, it is your story.
As a bonus, I'm also going to put in a word about dialogue tags, because they deserve editing attention too.
• Use the simple: Said. It works. You may be tempted, but don't screw with it. This is one word it's fine to use a lot as it disappears from sight. A few deviations for flavor now and then are fine, but should be used sparingly, as should adverbs associated with them. I once read a book where one character "said quietly" almost every line of dialogue. It drove me nuts.
• Instead of those telling adverbs and constantly relying on tags, use action beats to help flesh out the setting, add visuals to a conversation, and express emotions.
Timmy slammed one of his blocks on the table. "I don't want to go to bed."
Jane scowled and her hands formed into fists. "I think you'd better apologize for that."
• Tags and beats can go before or after the dialogue, whichever works best for the flow.
• Avoid adding too many tags or beats, they can bog down a conversation. For example, if it's a longer conversation between two people, using a tag/ every third line to keep us on track of who is talking works just fine.
• Use beats and small doses of narrative to avoid talking heads. Conversations with no description can read like a monotone phone conversation.
• As you edit make sure it's clear who is talking, and try to make the dialogue sound natural for that particular character - they probably don't all phrase sentences the same or perhaps some use different words for things (think lords and peasants). It's easy for the voices in your head to all start sounding the same halfway through your novel.
What is the most distracting dialogue tag you've seen in a book?
