I did create a long question on Stack Overflow which took me about two hours and then I wanted to publish it. Unfortunately it suddenly showed me then, that I am not allowed to post more than eight links and not any pictures with my current reputation.
My question contains about 15 links and three screenshots and it makes not much sense to post it with less information.
Why is this information not shown during the creation of the question?
I would have noticed this limit much earlier and I would not have spent so much time to compose a question which I cannot post later.
I was in the meanwhile able to post my question on Stack Overflow by removing links with backticks as Rene recommended. It caused me then further delays by system-messages like "You can only post once every 40 minutes." and "You can only post once every 90 minutes." even I did not post any questions there in the meanwhile.
I think there is some potential to improve the UX on the Stack Exchange platform.
