I'm getting timeouts when trying to upload larger files to your store.
I tried to move some of my assets to your store today, but I ran into some trouble:
The pack I wanted to publish is a somewhat large file (60+ mb). I can only upload about 50% of it before it times out.
I'm using Chrome, and I have http.request.timeout and other related options set to well over 10mins. Before changing these settings I got a timeout error. After I made these changes the upload repeatedly restarts at 0% every 2 mins or so. Pretty sure it's not my connection - it's the first time I ran into timeouts trying to upload stuff. Then again I might be wrong
In the end I used the web URL option and sent the file via Dropbox, so well done with that one. But still uploading shouldn't be a problem in the first place At least if the page claims files up to 500mb should be just fine.
Hope you can take a look at this. Other than that - cool site you have here
