Sig post?

I was wondering how you post a sig +o i have been trying different ways but none work F4 (and what lvl should i be to battle arena)

Zopickle if you made your signature try uploading it on a site like photobucket
if you made it off a site they should give you a few ways to upload the code like
direct link and all of that

And to battle in the battle arena it really depends on your stats
if your pure str build try lvl 12 -14 ish

i got it =D thx =D
