What does it mean when a thread is sticky (it has a small push-pin to the right of the title)?
usually it means that it is a particularly important thread.
Sticky threads will stay at the top of their given forum.
For instance, click over to the “easyC Technical Support Q&A Forum” (https://vexforum.com/forumdisplay.php?f=31), and you can see there is one sticky’d thread which will always appear at the top.
Moderators can sticky important threads they want people to read first.

You should have put it in the FAQ. More people are probably also asking similar questions, but too shy to make a new thread.
