Maybe I was a bit harsh but you are aware that this board has IDs based on your IP address, it makes it very easy to spot you. Prehaps you don't know that you can expand the text box to type more characters, either way you look like a retard. I'll answer you're original question, you open the link to the captcha in a new tab, then when you get the sucess message close the captcha tab and then click OK in the authorisation box and then you can post. If you want you're form information saved for whatever reason look at firefox add-ons.
Just relax and lurk for a bit, pick up some anime and read some manga. It's not about fitting in, it's about sharing something you enjoy with like minded individuals. As an anon, it's not about who you are, it's about what you post. Posting shit like this >>3371 is just going to piss people off. Most of us are here because we were sick of reading it on 4chan.
