Hi Laffett! Which megaserver are you on? If you are interested in RP on the EU megaserver, Daggerfall Covenant, you should come to Wayrest and join Stormhaven RP. If you are more into the Ebonheart Pact, then you should check out Ebonheart-RP. I am not aware of any all-werewolf or all-Khajiit guilds, but you will definitely find interesting RP (as well as fellow werewolves and fellow Khajiits...)

Checking which megaserver you are on is fairly simple. When you open the game launcher, click on the "settings" button in the top right corner (the icon that looks like a cogwheel). Under "options" you should be able to see which megaserver is currently selected, whether Europe or North America. That is the megaserver on which you are playing. If you want you can switch to the other megaserver at any time, but using both megaservers requires installing the game twice (and therefore twice the amount of space on disk).
