I think the issue is that the video files are being hosted on the server so that greatly increases the load that's being consumed for each pageview.

If you host the videos on something like youtube or dailymotion and then embed them it will take the load off your server. Just keep the originals in case they get taken down so you can switch to a different service. Hope this helps! Feel free to PM me if you need assistance.

For sure. If there's any other kind of help you need, though, you should mention it. I'm sure there are a lot that would be happy to help. I think a lot of us are looking for an outlet for our (highly overlapping but not super widely available) skillset to contribute how we can.

If this is your site, I'm willing to help make it scale. My email address is in my profile.

Good addendum (which causes to donate to) after the site is back up and running!

If you need devs please let the community know. There are probably a fair number of people here that would like to help.
