Not being nitpicky, but OTFCC was the failed venture by Glen Hallit when he forced the Hartmans to give him full control of BotCon.
If there is an acronym of the current mob, I think it is TFCC - it is official, but doens't seem to need to say it in its title.

I got this email the other day from the BotCon people:

Date: Mon, 11 Feb 2008
Subject: Update to all TCC members

This is going out to all TCC members BotCon info:
The Transformers Figure Customization Class for Wednesday and Thursday are now full. We have emailed everyone who got a seat in the class.
We still have 11 seats available in the two day Molding and Casting Class.
All classes are from 9am-5pm.
If you request on your registration form a class that is full, you will receive a call to see if you want to convert to the other class.
All tours are still available.

At least it means that I definitely got into the tours (they don't usually get a huge turn out for them), but at least it will give me something intesting to do while I am there.
