hello admin i want to start a forum but what are things i need i don't know?to discuss forum related questions which section i have to use?
Forum management could be one. If you have problems regarding the marketing aspect of it, you should head down to the general marketing section.
orumw management wont teach you every aspect since its limited to few users(because of less interested, specific issues) I would suggest you to visit it and post the questions there but you may try google as well...
