It can be helpful, but with several guides people will create on the board, there's no way it does the job it intends to do, which is finding what we want without going through many pages.
It not be only can be helpful , it would be helpful if new Users know how and where to Look.Mostly the new Users have no time and want there questions answerd quick , if they dont get an answer in 24 Hours they dont care anymore.
Its not an thankful job when you made some guides or helping others if they only here for one question or problem they have.
It can be done in a way that by restricts posting access in that section so regular users should only be able to read, while mods or someone who is assigned for the job can post the link to the actual thread where it is created along with it's title so duplicated guides can be avoided so less pages to go through.
If you restrict new Users to mutch , honestly Users will be afraid and rejected about it.For sure it would be helping against Scam Account or Users that are try to Scam others , but thats why the Community here to warn others
