Just to clarify.
I never suggest this be a members only forum, what I said is IF this was a members only forum, folks might be more willing to use their real name. See my original comment below.
If it was a club forum and you needed to be a SAAC member to access it more people might be willing to use their names. I prefer to have a level of anonymity when everything posted is open for anyone with internet access to see. But that is just me.
That being said, if this was a SAAC members only forum, fully supported by the club, I'm sure there would be a way to have some public areas where anyone could visit could post a question or comment without being a club member.
Even if there wasn't a way for the public to access the forum, the SAAC homepage, which anyone can visit, lists the contact information for the registrars.
So what we have a is a public forum for anyone and a club for dues paying members. If and how you want to participate in either, is up to you. There are no stated rules or requirement for user names on this forum. Simple.
