Screenshot, how do you post one

There doesn’t seem to be an option to post a screenshot and I need to post some.
In regards to the in-store shop showing really strange symbols and weird prices too.

The thread, explaining how to do this, has now been linked to around 180 times…

Back when it had been linked to around 100 times, I queried whether it could be pinned…

Well for clarity purposes I was trying to post a screenshot for a bug report in regards to strange symbols in the ingame store with prices that don’t exist of $69 with a whole bunch of @ signs with the number 517 included.
I do appreciate your help though.
Thank you.
