I get a fair variety of questions here at cpony.com, but there are a few questions that come up fairly often, and I thought today I would answer a few of the most common ones here.
Once you have joined Fetlife and setup a profile, join some of the global pony play and animal roleplay groups and get involved in them: introduce yourself, ask questions, try to answer other people's questions. Some good animal roleplay groups to join are: Pony Play, Ponyplay, Pet Palace, Human Animals and Owners, Puppy Play, Human/Animal Roleplay.
Also consider joining a local animal roleplay group so you can interact with animal players near you (e.g. Stampede or Bay Area Petplay if you're near San Francisco, Austin Pony Play if you're near Austin, L.A. Pony & Critter Club if you're near Los Angeles, Ottawa Pony and Critter Club if live near Ottawa - you get the idea).
I also recommend registering at The Human Pony Registry, which is dedicated solely to pony play. The THPR is somewhat like a breed registry, but is open to all ponies as well as trainers and owners. In addition to the registry, the THPR has articles, stories, photos, and videos to keep you occupied.
Kidding...sure, there are lots of great ones. Here are a few: Humanpony's Tumblr (great selection of everything pony play and updated regularly: photos, videos, stories, places to find tack, etc.), The Human Pony (book), Sir Jeff's (everything ponygirl - from stories to photos), Fetish Pony (great informational site), and JG Leathers (lots of cool stuff especially if you're a gearhead like me).
I also like Ponyboy Rusty's blog, Pet and Ponygirls (paysite), The Human Pony Registry, Ponygirl Lyndseys Corral (great informational site), and Five Case Studies of Pony Play (book).
Do you have a question not included on the list? Let me know, and I'll do my best to answer it!
