What's the protocol for replying to a member request?
/Please reply within 48 hours to all responses to your posted offers and requests. You don’t have to agree to every exchange. It’s fine to say, “I’m really busy right now, sorry!” But it’s important to reply quickly. If you can’t do the exchange, the other member knows she can move on and contact someone else.
If you are going away or won’t be available for a while, you can mark yourself “Inactive until [insert date]” on your profile page. That way you won’t get responses you’re not able to reply to.
Also be aware that your bio page notes how often you’ve responded when emailed. If your track record is 3 times out of 10, some members may not reach out to you. So do reply quickly, whether to say yes or no.
