I know hosting servers isn't cheap, it would be wonderful if there was a way users could contribute to the running costs in some way (e.g. buymeacoffee or Patreon). I certainly would like to :)
Thanks for the thought. For now I'm happy to pay the cost out of pocket, to see how things go and what the actual costs will be.
If it turns out that the upcoming flood of reddit refugees mean it isn't feasible and I need to shut it all down, I'd rather not have taken anyone's money.
