your current membership...

Want to change that generic,

"Your current membership (Non-member) doesn't allow you to view profiles."

 This is what  you see when you set certain pages where non members can't go?

Entice them to join the site with something more suitable that redirects them to the join page.

Make sure to input your site URL

• _ACTION_NOT_ALLOWED

Looks like this..

<div style="width: 80%">Your current membership (<b>{2}</b>) doesn't allow you to <b>{1}</b>.</div>
change to this

<div style="width: 100%">Your current membership (<b>{2}</b>) doesn't allow you to <b>{1}</b>. <a href="http://www.YOURSITE.COM/join.php" target="_self"><strong>Join up today! It's FREE</strong></a></div>

 recompile..

Very nice idea but... I'm hesitating using it.  Are you absolutely sure that message only appear for site visitors, i.e. not logged in?  

I just tested it... for my site, the same message appears for both visitors and promotional members... due to the membership levels "Actions" settings for my site.  If you only restrict non-members then your idea will work great.

 That's exactly why I did it, for guest and promotional memberships.

Of course your welcome to change the link and added text to what ever you want, i.e.

"You either have a free account or are a site visitor..." 

it's a common sense thing here, use it the way that works best for you, I also use PAC module heavily and changed that to reflect that they are just a guest..

[edit] I also don't use Promotional accounts..

PAC... a profile access control module?  

I did try several "common sense" ways to use your idea but none (that I could think of) seemed to fit a situation where the person could be logged in or not logged in when the message is displayed.  For example, if you have that message display for people logged in as promotional (or standard) members... it's confusing since they've already joined the site.  

What would be nice is if the person is not logged in then they see the message you suggested... but if they are logged in then they are forwarded to the membership page to sign up for a paid membership.  It's probably possible to simply link to the membership page then somehow, if the person is not logged in, send them to the join page instead, i.e. if loading the membership page fails, redirect to join page.

Your idea definitely has potential... I just need to figure out how to best use it. 

I get it... PAC = Page Access Control... yes, a very nice module.

 OK, your a guest on my site, you try to view profiles page, browse.php a favorite to look at. I have that page locked out with PAC, so..

you get the message that you not a member, your sent to the join page.

If you want it to say, "please up grade your membership" then put in a redirect to to the membership page.

With PAC, and membership levels, laid out properly, the options are open.
