In case you missed it, here is the recap to this week's chat. The original post is below.

It's another week, which means time for another #OFChat. This week's topic will be in line with our multiple-part BloodFile series: We want to to talk about blood.

Check out our entire series on our BloodFile page, then join us Wednesday at 2 p.m. EST for this week's chat.

Here are this week's questions:

1. Do you donate blood? Why or why not?

2. Should more Canadians donate blood?

3. Should the ban on gay men donating blood be lifted?

4. How do you think Canadian Blood Services can get more ethnic diversity in its blood donors?

You can also submit your own question for consideration by tweeting @OpenFile before the chat or tweeting @sarah_millar during the chat.

The hashtag for the chat will be #OFChat — make sure all your responses are marked with this hashtag so others following the chat see your responses. You can jump into the conversation yourself, or retweet others' views you agree with (or disagree with).

We recommend using TweetChat or http://www.tweetdeck.com/">Tweetdeck for the chat — it will make participating in the chat easier. If you want an idea of what to expect, check out a transcript of last week's chat.

We hope to see you Wednesday!
