I don't know how many people are aware, but our guides are not paid customer service representatives as in other games, but volunteers who effectively waste their own spare time to make our life nicer and easier in Xsyon.

And at least some of them are amazingly helpful and more than once I thought that I would love to have the possibility to just buy them a coffee or a beer or a round of whatever they drink just as a small way of saying thank you.

That's why I would love to see an option somewhere on the site to <buy a coffee> for a guide of our pick (it's a thing I saw on many sites where people volunteer their time and even do it by myself on one of our sites) - it's basically a small (dunno $3 - $10) PayPal donation that, at the end of the month, would end up on those specific guide account.

In order for guides to not tend to be more "friendly" towards the people that keep donating, the donations may be anonymously, so only you (Jordi) would know where they come from, while the guides won't know it.

How much time will it take?

Definitely less than four hours for a web programmer who is familiar with PayPal API. If really needed I can provide the code for it since I have a similar feature implemented on one of our sites (it's a multi-person blog where readers can donate to an individual author)

How could this affect things?

In the worst case it won't affect them at all. Only a couple of people will donate, the amount will be insignificant and you may drop the feature all together after one month.

In the best case the guides will actually get something more than our gratitude from their work, (some of) them may be tempted to be more active and more friendly towards users so we'll all have a better customer support in game (now that now they're not friendly, but there are many times when there is none available for hours) and we, players, won't be so guilty every time we disturb them, knowing there is actually a way to say THANK YOU.
