EFA stands for Excuse For Absence. You would post an EFA when you think you will be gone for an extended amount of time. For example, you have a loss of internet and it could take a few weeks to fix it. If you have a way to let us know, please do so. If there wasn't a way to contact us, then please don't worry. We would assume something was up, or you were simply busy to come on. We understand that life would come before anything on the internet, so nothing to worry about there.
The EFA is simply to ensure that your account is not removed due to inactivity. This community is friendly, and we are understandable should you not be able to post EFA here.
If you cannot post here on the site, there are many other ways to contact friends here. In the Biographies, you will see that users have accounts elsewhere such as DeviantART, FeralHeart, IScribble, etc. If you had an account an administrator has, simply alert them there and we will add you to the first post list of EFAs and your account will not be counted as inactive and neither will other accounts you may have control of.
