Combining two (2) Form Cs?

I am filling out two form Cs on my taxes and would like to just combine them into one. The expenses are pretty much spread evenly among them anyway, and it would be tough for me to say where the line is between them if pressed to do so.  A long while back I was doing it all on a single Form C, but one of the message boards I run involved a Board Of Inquiry forum that was being used to out bad guys and scammers in a particular industry.  Of course those bad guys would threaten me with lawsuits time and time again, so I figured maybe I should separate that endeavor into it's own legal entity just in case I were to actually be sued.  But for reasons not relevant here, I eliminated that Board Of Inquiry forum, along with the lawsuit threats, and right now filling out two Form Cs is just an unnecessary complication.  Sure would like to simplify things a bit.

 

So any caveats concerning just combining everything under the main business entity and dropping that other one?  Any hoops I need to jump through?
