@Joslyn, you're mistaken.
Although you might be able to find a URL you like for $15, you can't set up a site like this without greater investment--even if you used a freeware forum software--because there are other costs and expenses. These include:
--bandwidth (hosting), which will come at a higher price once you get some traffic and/or begin hosting photo images and files;
--a content management system (CMS), which is what you see as "the home page" but is actually a shell and indexing system that surrounds and...may be intercoursed with, the whole site;
--time, to program, to moderate, to anti-hack, to de-spam and to comply with a variety of accounting and verification protocols that begin the moment you decide to accept money for anything (not counting the old school, under the radar, "bros, we need some donations for the server's yearly fee" that small sites can do);
--and then, if due to time or other misfortune, you find your forums to be successful but mired in a CMS and/or BBS software that isn't updated or updateable, you'll have to migrate all the databases and data into new, different, potentially incompatible but much nicer software. This will come at the cost of time, heartache, stress, money ranging from a little to obscenity and will likely require you to redesign the site's CMS.
So, it's not **quite** tossing down fifteen bucks and ~BING!~ out pops a wonderful site that has lots of people coming to it. In fact, for a site that, like this one, is mired in an old CMS and lousy BBS software, it's not like that at all.
But hey: pretty much everyone here is an internet lover. You go girl! Make that new site and include the free classifieds section. You know we'll all check it out, because we will! Maybe that would create some incentive for the millionaires owning this site to put down their cigars (on that gilded ti stand over there at the side of the tee box) and make a better pen for the golden goose? I'll help, too: when you reach 30k monthly uniques, zap me a screenshot of the Analytics and I'll buy a banner ad for $10/month. I put my money where my mouth is. I might even post a classified ad.
Now, @ the millionaires: do what you want with your Classifieds, but please become aware that the longer you wait to push the Agony Button, the worse and more expensive it will be to update and de-lame the site.
Trust me, I know these things.
