How to highlight threads?
 

How to highlight threads? Is this a plugin? If yes, which?

Examples:

In addition to this, is it somehow possible to make this highlight blink? Like flashing lights? Meaning highlight on, highlight off, highlight on. Like a flashing amber light on a traffic signal.

I have a vBulletin product for vB 4.2.x here that will allow you to highlight threads (and add additional CSS):

Additional Thread Tools

Thank you.

Is this a paid or free product?

I see it does the highlighting that I mentioned in OP. Can it also do the flashing thing I mentioned?

All of my products are free and supported. The product to which I linked doesn't support blinking backgrounds by default, however you could likely add a flashing background via the additional CSS you can add with the setting "Additional Threadbit CSS" and adding some kind of animation CSS selector to the page.

Thank you. That's great. I'm installing your product now.

I am not a techie and hence can't do that on my own without instructions. Could you be so kind to give me step by step instructions on how to add the flashing highlight feature?

Just installed it. Absolutely wonderful thing. Great job.
Any chance I can change the pink highlight to yellow highlight?

Okay, after you have the product installed, add a plugin as follows:
