How awesome! Welcome to the Arena!
This is an awesome site for ANYONE into toys.
There are seperate forums for MH dolls as well as other dolls, Ponies (obviously) and LPS, but even without specific boards for toys, most of us here collect vintage toys and some have collections of all kinds.
Many of us collect Fairy Tail Birds, Monster High, Fashion Star fillies, Cabbage Patch dolls, Breyers, Smurfs.. you name it and one of us is probably an expert in it!
If you ever need to find an ID on a toy, post in the off topics section, I have gotten a ton of questions answered there :3
