I had the same concern....but it hasnt changed my posting habits...so lets all lighten up and have some fun....
The hijacking that concerns the mods (I think) is the type that turns a thread into a playground for 2 or 3 people to flirt and play with one another turning it into an entirely different one than envisioned by the originator....
For that you can start your own thread in the silly forum...there are hundreds..... There is no need to turn each thread in Gen dis into that type of banter....doesnt mean we can't have fun here folks...
