Workin' on a new stackexchange site (gamedev), and my rep is starting level (thus low). I was trying to post my question, but turns out I can't create any tags that I find appropriate to the question (after I submitted once, and answered a no-spam captcha once or twice). Then it turns out that I can't post a question with no tags (second submit, and another captcha). so then I had to open up a new tab to read through the possible tags for the site, pick a really vague one just to fulfill the requirement, and submit again (third submit, third captcha). So finally after 3 submissions and 3 captchas, I've gotten my question through the tag-specific-requirements hoops.
This was an annoying procedure for me, so for a newbie I'm sure it would be disruptive.
