Software suggestion (re: topic drift control)

I would like to 'second' this motion. I have very often had a paragraph written in the reply field and then realized that I am responding to something totally off topic; and therefore cannot reply with what I have already been working on.If you can nip the first off topic people's responses (with a new built in system) in the bud, then you can also halt the subsequent off topic stuff as well.I would be in favor of a red text statement somewhere near the top in (or near) the reply field. Being able to access the OP is also important.

Okay, I'll use these solutions. I use firefox and can usually solve these type of situations by holding the Ctrl button and left clicking a link. This then opens up a new tab with the data I need. I had hoped there might be an easy way to show the OP.Maybe some sort of bold statement could be shown reminding the poster, as they write, about staying on topic. Most of us don't need the reminder, but noobs come in without reading any of the forum guidelines and then start posting off topic. Often a long time forum member then mistakenly responds to their off topic stuff. Oddly, not responding at all is in error as is stating over and over to remain on topic.
