You will find a ‘Sticky Topic’, generally called a ‘Sticky’, at the top of a message-board, usually containing pertinent information or Q&As to previously over-asked questions, for sake of keeping the board running relatively smoothly. On some-sites' boards, it is required that as a new user you read the Sticky rules by clicking into the Sticky Topic before posting, so as to dissuade spam posting and such. Note that there can be more than one Sticky Topic for any given board, though usually one alone covers all utmost essential info that need be said.
Also to note, the word ‘Sticky’(the more abundant form of the word ‘Sticky Topic’) can act as a past-tense verb or as a past-participle by adding a ‘'d’ to ‘Sticky’ (‘Sticky'd’). Usually transitive. Can also be a present-tense verb, appearing the same as its noun form (‘Sticky’). ‘Sticky Topic'd’ is not an actual word, but people would know what you meant if you used it.
