 Libravatar is a free and open replacement for Gravatar. It is a service where people can store an avatar image for their email-addresses. These avatar images can get looked up for example in comment functions, profile pages, etc. on other sites. There exists a central installation at [www.libravatar.com](http://www.libravatar.com), but you can also host it on your own server. If no avatar was found Libravatar will look up at Gravatar as a fallback.
 There is no rating available, as it is on Gravatar, so all avatar lookups are g-rated. (Suitable for all audiences.)
 
-PHP >= 5.3 is required for this addon!
-
 You can not use the Libravatar and Gravatar addon at the same time. You need to choose one. If you need other ratings than g you better stay with Gravatar, otherwise it is safe to use Libravatar, because it will fall back to Gravatar if nothing was found at Libravatar.
