Thank You

I'm sorry I'm not a better English speaker to really express how impress and grateful I am for the oportunity to use a tool like zoho. I am in the real world creating real applications for the benefit of thousand of people related to the organizations I work for (worker unions). But I have an important question, I'm doing a lot of work and I'm depending in zoho for critical and serious matters, how can I be sure you will be there for a long time, how can I help to sustain you, there is a link for donations, I did'nt see it. If you have it, it is not too obvious...
