MATE Desktop Environment is totally free and everyone involved are volunteers.
Please consider donating to the MATE project. It is nice to have the effort we've put into it recognised. Any money raised will be used to cover hosting costs, any hardware procurement and possibly travel expenses so that members of the MATE team can attend relevant conferences.
We don't ask for much, it is at your discretion.
Many of your have generously donated to the MATE project. We will be publishing a full list here very soon.
We will disclose how the donations were spent here. Full details will be published soon.
