I only donate gear I know I can spare, but I try to be as generous as possible. If I don't need it for a while and can replace it before I need it, I'll donate it. I try to do at least 1-2 donations a day, and I buy gear with credits in Shipments that I don't necessarily need so I can donate it. If I request something rare, I usually get it, because I've helped most people out. I never request gear that I'm unwilling to donate, like Mk 5 Stun Guns. I try to ask for more common gear so I don't burden my guildies. And I don't donate to people who don't donate gear themselves - I don't think it's fair to ask for stuff but never give back.
