What do you do when you open a forum? How do you try to get the activity going? Do you have a competition to start everything off? How do you get your forum out there in like one day? Do you just request a lot of different services at promotion forums like here?
In one day its near impossible. First of all you need to create your forum. People want to join something that attracts them, so a nice logo, and premium theme are a big plus. As far as generating activity you wont see a lot of progress immediately. It's a long process to get even a few active members. Your forum needs to have original content and features that you can't find elsewhere. It's hard work but if you're dedicated to your project you can produce good results. You just have to stick with it.
Also posting packages are a good way of increasing your post count, but that is only temporary activity. Chances are the packager won't ever return unless you request another package from them.
Ive only really opened (been serious about) 3 forums. 1st one was Forum Advertiser. I got it all set up and posted a few topics on it, then advertised it in a couple places. Then I opened The Island. That one I had a few friends help me generate some discussions before I plugged it. Same with my current forum Wober.
