Onto more important information...
Basically, he mentions that it might be a problem with PHPMyAdmin but after looking into things and doing some research, I found this...
It's converting into 'varbinary' with 150 character limit for the actual key which should be their SteamID64. I'm been thinking of a few ideas on how to fix this but I'm not sure if Xenforo requires this to be setup this way or what. I'm needing the CommunityIDs in order to grant my administrators flags on my servers automatically via SQL connection. If there's a method to converting this binary code (which I think is what it's called) to the CommunityID with any number of methods, I would like to know.
Any help would be appreciated, thanks.
