Free hosted realXtend Avatar account with a free Woman Avatar
realXtend has provided free hosting for your avatar for some time now, but it may not be very widely known. You can host your avatar shape, clothes, textures for free at realXtend project’s servers.
Use Avatar creation tool from the realXtend client software to save your stuff there. You can then use the account to access any realXtend world. This means that your avatar will travel with you from world to world, unchanged. Note: World server admins can override your avatar – this feature is meant to preserve world theme – for example in Ants world all the avatars may need to be ants.
Service provider: realXtend
Click the picture above to download also the Jaana Avatar model – you can use it with the free account! If you want to generate your avatar from a photo, follow the instructions in the Maxping article where Sylvester Stallone avatar was created as an example.
License: Use at your own risk. 
Is there any information about what realXtend worlds are hypergridded? Are there any main public grids to log in to? The avatar above — the signup page doesn’t provide the name of the grid it is on.
Also, are the realXtend worlds backwards compatible with the OpenSim grids?
Thanks,
