It seems that all the people making promotion forums nowadays just want to create them because they want a large community to be 'the boss' of. Not because they want to actually help other forums succeed.
The people who have no knowledge of forums or set it up to run a large forum usually give up after a week as these type of people are always impatient and expect 1000 members and 50000 posts over night and when they don't get it, they just close it.
Topics are really what you should be aiming for, as they in turn generate replies. The more replies you get, the more active your forum becomes, enticing more members to join. :great:
You can do that, but how unproffesional, if you want people to join your forum get some good content on there and make sure you know what your doing.
Take the gaming genre for example, there are sites like ign and gamespot which control the majority of the gaming market, but there are other smaller sites which still have an active user base of over 50,000+ and growing. It's not about competition, it's about content, friendlyness and why they should join it over the rest.
Just my opinion but if you want to do that you can. Promotion forums do succeed abit better them most newer forums out there as everyone loves to promote for free, but it's hard to establish an active community base. If you want a easy community to run and manage then do something small, then go for big. 😉.
You need content, content and content! Search engines love it, new members love it and your database loves it! Having more topics, discussions, polls and other exciting 'things to do' will really attract all your guests to register and join the party 🙂
It's all about initiating a unique community - one that embodies its competitor's traits of highest quality and popularity, but still manages to bring to the table HAWT new features.
