Dreamhost has what they call a "one-click install" system for us to be able to install some very popular packages into our web space without knowing anything about installing software.
....
The "easy" installs are basically totally maintained by Dreamhost staff so if you can live with the more limited addon and template options, they are the least maintenance. Ironically, they are also the highest performance options as well - supporting the highest traffic.
I would like to point out that there is more forum software out there, however. The only other viable option is Simple Machines, which I actually prefer. (There are a variety of reasons, for example add-ons are a breeze, whereas with phpBB you have to manually install them.... but I won't get into them here.).... if you use a bit of shell, you can actually get a forum you upload yourself running faster than one done by the 1-Click Installer.
For webhosting, you should be fine on your regular, $10 / month account until you get many many members.
There's only one hosting plan, which gives you 500 gb of hosting space and 5 tb of bandwidth. I figure $10 / month, because that's what it is paying on a yearly basis, but if you pay in advance you can get it for as low as $6 / month. Not to mention the $50 off you can get from a variety of promo codes.
Good luck with your new site!
