Yeah, what he said. And frankly, any downtime here is typically very short compared to that of my previous hosts and things tend to fix themselves without me even having to contact support. (Which is good when I'm not around much.) I honestly have no complaints about Dreamhost.
But yeah, as long as I'm paying for all this out of my pocket, there's gonna be some downtime occasionally. I can't afford a good dedicated server, nor do I want to spend time administering/managing one and I certainly can't pay someone else to do so.
Well to be quiet honest, despite my intense hatred of Dreamhost (for reasons I won't get into here) I think it works for a budget operation like this. There's not really any personal or professional risk to you from the downtime, or the constant threat of losing your data (as happened to ~250 Dreamhost users a few months back).
I really see no reason to switch to a dedicated server (Which is around $100 USD a month at the cheap end). Though I will say the administration and managing of it is much simpler then you might otherwise think.
If you ARE ever interested in making that switch, Amy, let me know. We wrote up a White Paper for I-Games on the subject that covers everything from the migration of the forum software to the migration of the database, to the programs both necessary and recommended, and all the problems and difficulties we ran into and how to avoid them in the future. (And since we have you to thank [and I mean this sincerely] for our switch to the SMF software, it'd be pretty much a carbon for carbon copy process for you.)
