I am not sure if this is naive, feasable or even wanted
MODX LLC have a donate and support button on the main website which links to
this page
I can only presume that the donations that are made here all go into Revolution and other projects e.g. Cloud etc.
There is (if I am right in saying) no money for Evo development, meaning, the work that the community developers are doing isn't being honoured in any form, other than a "thank you" from one or two users.
Is it not possible on a community basis to get a donate for Evo button for those who use and wish to use Evo for the next couple of years
Where all donations are split between the community developers who contribute to Evo
This could help in getting Evo "up to date" or at least support the forthcoming major changes that need to be made for Evo to work in the near future.
I am not sure what would need to be arranged, but if a MODX LLC member could read this post that could/would be a start.
