Yeah, you gotta validate before you can post. Though, if you had an issue, there is a forum that you can use to request manual validation (because some email providers no longer receive messages from this site).
But anyway, welcome to YCM.
I'm Sakura, the moderator for Custom Cards, and one of the Super Moderators overall.
Before you post further, I have to ask that you take a look at the rules, both the general ones and any section specific ones. Most of them are common sense, but give them a look. As you're going to likely be in Custom Cards, make sure you read over the specifics in there, because there's a lot of stuff that is exclusive to the area.
If there's any questions, you can ask a staff member or a veteran of the area. Though, if you are going to CC, then you can just ask me directly.
Have fun and enjoy your stay.
P.S. The Other TCG forum in Custom Cards would love your CFV / Buddyfight cards.
