Hi flavie,
Advertising has to be paid for whether it be on billboards, newspapers, TV or the Internet. The website of niklasber linking people to commercial sites will normally generates income for the owner of that site, in this case niklasber, so posting it is spam and hence its removal of the link by my collegue. If the site is in it's infancy it may not at the moment generate any income, but if it proves sucessful, it most certainly will.
Chordie promotes and advertises two guitar tuition courses, Jamorama and JamPlay. Both of which are tried and tested and and known to be fair and honest with their clients. From posts we have seen in this Forum it is obvious that some of the others are not trutworthy.
Any newcomer, like yourself, wanting help will get it completely free from the generous Members of Chordie who are always more than willing to share their knowledge and experience with others and to help and encourage them to improve, simply by asking in the appropriate section.
Roger
