What about expansion of topics on the forum?

It seems that forum audience extremely expand.
Also to make refit of some machine, you need to have knowladge in servodrives and as in my situation in repairing of old servo.
What do you think about expanding forum in some new aditional topics, for example
- power electronic devices (that include servodrives, stepper motors, freaquency drives, problem solvement and their repairment)

May be other topics about programming (linuxcnc, C++, python, micronotrollers in junction with linuxcnc, so on), how do you think?

I think Arduino/USB has it’s place. Definitely not related to motion control but replicating joystick/keyboard control pendants.

Anyone that mentions USB motion control or argues that Linuxcnc must support it should have to do some sort or meaningless task for redemption.

Maybe a subtopic for each of the more popular Mesa cards ?

I wrote a lot of topics in general "linuxcnc cnc question", this topic really consists a lot of different information that could be told "unsorted data".
CNC has a lot of braches that could be discusses separetly, I think.
