You're fine. Every so often I'll go through and check, but I don't see the need for it to be mandatory to link me your character on the server. You questioning it alone was proof enough for me to see that you took your character's server into consideration before joining the group. I'm not worried. Besides, I think majority here, at least back in the day, came here and joined from posts I made on the wyrmrestaccord.org forums. So you're good hun.
Oh and welcome to the server!
