What Are 'members'?, How do I become one? Options

Hello:
When I try to look or read the 'member's lounge' It says sorry but you cant.

Is a member:
1) one with more than 30 posts (needed to read blogs)
2) one that pays a membership to the esoteric library (to download posts)? (so which level of membership or $ ?)
3) some other criteria?

I would appreciate some information on this...
Also I have spent several hours looking at the controls, replys and posts and I can not figure out how to add an attachment to a post (feeling thickheaded (IMG:style_emoticons/default/sad.gif) )

Are members the only ones with the ability to attach files to posts?

I really like this site, and most to the time I have just asked questions (and have gotten very helpful replies), and if I get interesting experiences (which I am hoping for) or come accross interesting information I'll post them here as well to contribute the best I can.

Thanks,
Traveller

30+ quality posts and you'll get access to most of what SMF has to offer (IMG:style_emoticons/default/smile.gif)

All members can add attachment to their post (member's group size quota allocation differs) and you can find the "File Attachments" feature below your post box when you're starting a new topic or when replying to a topic. Just browse and select the file at your local hard drive then add it to or within your post.
