What to do?
Let's say you know someone in the demoscene and you appreciate the efforts they do in and for the demoscene.
Also the activities they do are supposed to achieve a great degree of excellency in their execution, as their predecessors did, to maintain the previous level of quality - which all of us expect to see.
But they don't manage to do it once. Then you offer them your help and advices, and give them suggestions about how to solve the errors, without expecting any reward. You even don't ask them to appear in the website as a collaborator, you just want the things to be properly done.
And they don't even reply your e-mail to say "no, I don't want your help".
Next year they repeat the errors and you wonder again: should I help them? or should I let them be the laughing stock of the party?
Hard to decide, isn't it?
