In a recent exchange with RMS I tried to encourage him during his recent "re-cancelling" and ask how I and other concerned users can help.
He had a few suggestions, one was signing the github letter (can be signed without a github account), another was spreading https://stallmansupport.org/ whenever possible.
I will be adding that link to the signature of my email to try to get more coverage of it.
Other suggestions he had was having serious, non trollish discussions on public forums.
Also he suggested joining the FSF which I will be doing.
I would highly encourage you guys to do the same, non-student memberships are $120 a year which is less than $3 per week: a small price to pay.
Then as a FSF member he suggests encouraging them to support him.
I will be joining today, I see it as a small price to pay to support the movement and RMS himself.
