This has to be one of the most BS fund raisers I've ever seen in this game. I don't object to fundraisers at all, I'm aware that people can donate as they see fit but there is so much deliberate misdirection here.
"We have also been able to reduce costs by contributing individually where we can.."
What does this mean exactly? As far as I can tell the only expenses that aren't listed in the breakdown is the £40 it will cost kos and mike collectively to get to the LAN, and Mikes accommodation which is entirely separate. The tickets were given to you for free which is left out of this information (so potential donators are led to believe you actually bought something on your own), are you honestly asking people to believe that despite "caring only about LAN" for the past 6 months that the six of you can only come up with enough money for two British people to travel to a British LAN, and even go as far as asking for £60 for another British person to get to the event.. Considering one of your players just dropped £250 or so on a monitor that he doesn't need (at all) earlier this week, this is just bullshit.
"and shoving more people into a hotel room than is advised."
5 people in two rooms. Considering there is already next-to free "rough" accommodation at the event, asking for one hotel room seems entirely sufficient. Fair enough if you want to get two, but don't make it sound like you are significantly cutting corners here. This is one guy sleeping on the floor, maybe you rotate so it's a different person on the floor for one night each. It's completely disingenuous to even suggest that this is a noteworthy sacrifice, it's just carefully worded to maintain the farce that you've done anything or made any sort of contributions as a team.
You even ask for money for a PC for alle when he plays on a laptop at home, yet still try to maintain the impression you are keeping this as low-budget as possible? There are also numerous viable options for free PCs that certain members of your team definitely know about, but instead go straight to asking for money. I guarantee if you don't hit the fundraising goal, you will still have six players at LAN with entirely adequate computers and monitors.
It seems to me that you need roughly half of the money you're asking for, and the fact you've been talking about going to this event for so long makes it ridiculous that only kos and mike can cover/contribute to their own costs. I'm aware you had a "sponsor" until a few months ago and this will probably be the excuse of choice, but it's really not a good one when you consider what that sponsor was and how long ago that became obvious even to you guys. Also to be clear I'm not suggesting people shouldn't donate, I hope they still do because the event is better with you there but just be honest about the circumstances and most people will still donate to see a good event. No need to trick the rest.
