Hi. We seem to be covering the co-location and hosting fees so far, thank you. It's really appreciated.
I've not used any of the donations yet towards the cost of the physical machine we're using (I paid for that in full), but if we build up a bit of a buffer that might be sensible.
I had looked into setting up a "club account" and "club" to formalise everthing, but that involved a whole lot of paperwork and formal process that I just don't have the time or energy to work through.
