First of all, thank you very much for your quick answer. It brightened my mood somehow
Secondly, I'm sorry if my post sounded so negative. The initial goal of my post was not to be negative, even if I admit my frustration might have impacted my style a bit. I have just spent a lot of precious time trying to follow the guides which are obviously not complete, looking through the forum for similar issues, and then spent even more time trying to write this message and dealing with limitation after limitation. Sorry if it wasn't necessarily the nicest message but please understand the frustration it came from.
And yes, I fully understand there are rules for a reason. I also fully understand the first rule about the link limitation. Maybe, following your explanation, it should be done about the exact same link (as you mention), not different links. But I don't really mind the link limitation to be honest, it's not that bad, I just wrote them as plain text instead.
The real problem however was the image limitation. Unless I'm missing something, I don't see any logical reason to limit the number of images to just 1 ... what does the number of images have to do with spam ? And even if it did have something to do with spam and you want to limit them, why just 1 ? If it was something like 2 or 3 I would understand (for spam and also for space optimisation), but 1 is really too little to fully explain and show a complex issue.
Also, my goal was never to discourage new users from asking questions, quite the opposite actually. I am simply stating why I, as one of these new users you're talking about, was myself almost discouraged from asking a question due to these limitations, hoping it would maybe convince you to make them slightly more flexible (2 or 3 links instead of 1, 2 or 3 images instead of 1) in order to prevent new users from giving up halfway before sending their question like I almost did.
I think it's much more constructive to post it here than to simply rant in a private message.
Also, one other reason why I was a bit frustrated when writing the message is that I found several posts of people having a similar problem, and ALL of them had no proper answer. None of them had an official answer, they were all answered by Infinity, who unfortunately seemed to not really grasp the problem these users were having because he just asked questions about whether they were active or not, then told them to "click on Infinity" and send him user credentials. He is not to blame at all, he is "just" a user, albeit senior user, and just the fact he tried helping is already good enough. It's not like it's his actual job, he's just a nice community member and tried what he could to help.
Speaking of which, thank you Infinity for your advice, I will try that right away and let you know if it worked.
Again, I have no intention of being negative for no reason, I just wish to be constructive and bring my own tiny contribution to this forum by explaining what almost discouraged me to post here.
Thanks again to both of you for answering so quickly, it doesn't happen often in such forums
