Interesting idea....

Maybe the only "problem" with the suggestion IMO, is if the reply is OT, then the original post may be as well.

At present, only Agora can move a post to the OTB.

What I do on occasion, when posting an OT message on that board, if I feel it has significance and possibly of value to many is this...

On the main forum I start a new message:

"OT: check my post titled "XXXXX XXXXXX XXX on the OTB..eom."

It works pretty good.

Just a thought for you.
