In my opinion, unless you want to role play, you dont even need to pick a fursona. Just hang around the forums as the "human in limbo" or something
The sona that calls to you will come and will stick and then will go through 2 or 3 modifications until its molded perfectly to you.
Dont sweat it though and dont over think it! Once you have figured out what your inner furry is, PM me and ill draw something up for you so you can have that as your avi!
