I couldn't say for sure. I'd probably hide from all the other ponies during the first day and at night go to Twilight's house saying I'm new to Ponyville and asking if I can stay at her house for the night.
Yeah. The group really exploded over the past month or so, I guess it was only inevitable as the MLP fanbase continues to grow larger and larger.
for the most part the active members of the group have stayed the same, we've got a few more now but as you can see it's still not a very active group.
True. From what i understand though the minimum amount of episodes a successful series needs to have is 65, which is how many episodes there will be with the first three. Besides, most of the money generated with MLP is made with original content from fans, I don't think that Hasbro or the creators themselves are making all that much.
I really wouldn't want to see it end after just three seasons though. I'd like at least 5 or so.
