I've pinged the user in chat, so chances are they will now read your message.

If you really want to thank someone for a good answer, then you'll perhaps take the time to go through one of their questions and provide a good answer for some question they have.
Flattered as I am now, it is also very satisfying to read that another usable laptop was saved from its premature fate in the dumpster.
The environment would like to thank you back for 'repairing' it back into a more than halfway working condition.
And that means really all of us.
Cheers and keep hacking and sharing.
Recognizing someone here is a wonderful way to thank someone when you don't have an established account and you've already used the normal channels of a positive vote for the specific post in question.
