I created some internal boards for the staff where I answer their special questions or just chitchat with them.
I got a second full admin a few month ago and from time to time I try to make him a present.
Its ok that I do this job for nothing but I like the way he spends his free time to support me so I try to make him a present from time to time.
Could be something small and even a THANKS YOU is ok.
Its a little bit like in a relationship
