Let me start by quoting from http://www.paraglidingforum.com/faq.php#1:
Paragliding Forum is a real name forum
We're convinced that posting with real names gives more quality to the forum and adds extra value to the posts. Paragliding Forum was founded as a reaction to former forums where anonymous postings have destroyed any civilized conversation. That's why we insist for real names and why this is our Golden Rule.
If there's any doubt about the identity of a user, the name fields will be cleared and the user gets a warning at the next login, to fill-in the real name. Whilst the name fields are empty, the user cannot post and all posts of the user remain hidden.
Real names are only visible for registered users and hidden for search engine bots. That's why you should avoid the use of the real names in your posts.
I don't really know how to implement some of the automated features they use for hiding real names and barring posting when the "real name" field is empty. If those features were important, I could look into them.
The reality is that many of us (Bill, Sam, and Rick) already use their full names. Others (like myself and Joe) use abbreviations. Still others (like Scott and Ernie) use a "handle" but their names have been made available either by themselves in their posts or by others referencing them by name.
While I've certainly seen some bad behavior on paraglidingforum.com, I do think they make some good points in their arguments for real names. I'm not necessarily advocating one way or the other right now, but I think it's worth considering. So I'd like to open the topic for discussion and thoughts.
Thanks.
