That's true, but in any case I do not believe it to be a useful requirement. In the end, having a completed project will be beneficial to recruiting efforts as it is demonstrative of the requestor's skills, but if somebody wants to join the team of someone who hasn't had that particular experience, then it is no use to deny even that possibility.
Besides, not having completed a game doesn't mean you are unskilled. There are other ways to demonstrate skill.
And if someone wants to post a recruitment topic without any demonstrations of their own skill, then the worst that can happen is that they do not receive any responses. And if somebody does join a project like that and it turns out that skill is absent, it is not as if they have been tricked - they knew that there was no evidence of skill.
The fact is, having people without demonstrated skills post recruitment topics does not negatively affect the forum, and so I believe that requirements for recruitment topics would be unfairly restrictive.
That being said, informing Ash of the unlikelihood of receiving response without demonstrated skill was a considerate thing to do and I do not mean to discourage people from doing so, though perhaps there are kinder (albeit less humourous) ways to do so
