## Notes

It's been a while...
There would more releases and more features if you helped me.

I'm dedicating a LOT of time to NeoMutt, but I'm not getting any support.
The occasional "thank you", is heart-warming, but it doesn't achieve anything.

I'm tied up making large architectural improvements.
Each success simplifies future NeoMutt development.

However, nothing is happening around me and that's really demoralising.

I need help with NeoMutt.

Stop making excuses and make some time to help.
