Its about $30 a month with this package, but I don't know how much bandwidth we will use as of now. I will check in a week to see how much we used.
We have a limit of 500 gigabytes, which is a lot and would be about 16 gigs a day. I'm hoping that, that is enough to use.
1000 gig is $45-50 a month
2000 gig is $100-115 a month
We have a virtual dedicated server, which means we kinda have a dedicated server just for this site.
To go to a dedicated server, which I don't know if we will need now... or ever the pricing goes from $80 a month to $300 a month.
The two things we have to watch is the bandwidth and the speed of the site. It looks like this forum software is pretty fast and doesn't load a ton of stuff when you go to a topic.
