I think the helpdesk is a big useless mess what I try to avoid 99% of the time. I only open helpdesk if it really necessary, usually because of some strange error messages.
To find some structured information about how Corona works is just not possible in this form and (dis)organization. Hard to read with a very cluttered page layout, formatting.
I could say no offense and don't take it personally but I won't. I'm sure you are caring about educating your users, and I just wanted to give some feedback that it's going in a very bad direction. I'm pretty sure you can do better than this.
Please refer to the Arnold user guide or Vray.
I also attached some screenshots for easy visual comparison. :)
