Site changes

Don't know but 2 hours plus on site, then getting access denied when going to comment on the pcp thread doesn't seem like a spammer.
I seen that many guest online before, in the 20s seems to be pretty average when I look during day here.
6 of one 1/2 dozen of other, was just to bring it to Nunga's attention in case there's a glitch stopping commenters.

A guest is anyone that is not a member of the forum that is viewing the site. Guests can not post or reply to topics.

Generally you need to join a forum to be able to comment, so it makes sense that if they visit and feel compelled to comment that they join.

I was thinking a button to a redirect page, with a name only sign in, that gave you two posts before you had to join.
The site already separates the guests from members, so that's done. The redirect page would be a whole separate set up so new coding allowing a couple of comments per log on to page isn't much more script to add. It adds another layer.
General viewers could look on the usual set up.
As for scammers, deal with it. The Web ain't full of fluffy ducks all quacking nicely. Sure do what you can to stop them getting on site, but end of the day if you get scammed that's because you didn't do enough to check it out, not the site, not Nunga, not me but you.
Its part of the Web, though it's not nice for all you know someone could have signed on as a member and be biding time, waiting to pull a scam.
To many limitations will stop site growth, limit input and become a closed group of people.
