You can ask around for trainer cards. Alot of members make personal cards for others which is very thoughtful of them.
You can select a avatar in your profile. Go to the very bottom of your profile page and there is a button that say's ''Show gallery'' from there on you can choose any avatar you want. If you want one made personally you will have to ask around.
This thread should also be moved to the ''Help thread''. Whenever you need help on something always post it in that forum unless its pokemon related.
If you have anymore question just PM me and ill take care of it for you.
