I found this on Facebook at the weekend and thought that this site deserves a bit more attention This site attempts to provide a directory of all online tabletop gaming websites in one easy to navigate location. Look for yourself: The Repository
You can search the repository for tags like figure scale, manufacturer, topic etc. It is very recommended. Alas as it is very new there are still a lot of entries missing. The people behind this site therefore ask for help in developing the repository further.
