Fansubbers have 2 main costs really...
1) Buying Region 2 DVD source for Proje3cts
2) The cost of paying for servers / IRC bots
Time is not considered a cost. We do this for free cos it's fun and we enjoy the shows that we work on. If we accepted $$ for the time that we spent on stuff we'd be basically making ourselves pirates and would just be as bad as the DVD rippers / HK pirates that are so prolific at the minute.
As far as the DVD's is concerned personally I feel wrong about asking for donations for that kind of thing. I'll pay for that out of my own pocket. As for the bandwidth costs thats just a cost we have to bear or we'd have no distro.
For example I'm paying $35 a month for the server that I run. That runs out at a yearly cost of $420 a year and thats CHEAP but I do it cos it's fun and I like messing around with dedicated servers.
However to answer your question, do we accept donations directly? The answer is NO. However if you chose to invest your money in renting a server / IRC shell from somewhere and wanted to use that shell to distro our releases we'd be more than grateful for the extra distro resources and theres the added bonus that people who distro stuff for us get a few little perks as well
