We are terribly sorry for the inconvenience. It seems that we have forgotten about this service we have provided in the past and never transferred it over to our new server during our many migrations. However, we now have this service reinstated. We are still not certain that a centralized database has been built yet, but please feel free to continue to use this service if necessary.
All of our development for anything theme related has been dropped and communications between other parties have ceased. However, we would like to have this jump-started again. If you are still interested, please contact us at admin[at]xengi[dot]org for further information. It is still in our best interest to provide a very accurate database for the IOS theming community.
