Introductions-thread?

[Pmt111500]

Should there be an introductions thread on the forum? This would not be obligatory to allow trolls, misinformers and timid people to continue writing to the site but might serve as an additional check. In the beginning of the forum there was something like this, though most thought it was unnecessary,  disliked and disregarded. An open forum shouldn't need to have one, was the general gist.

This thread would have to have a rule allowing only one message per participant.
