"Wall" widget that appears in your blog's sidebar acting as a cool shoutbox for your visitors.
It creates a draft page in your blog under which all comments are stored.
= What if I don't use widgets, how do I code this to appear in the sidebar?
Just put this code somewhere in your theme template, probably sidebar.php
= How does it combat SPAM ?
The same way your usual blog comments work. You can enable comment moderation. Or you can install one of the spam blocking plugins like Akismet.
= How do I change it into a shoutbox/chat?
Just set the refresh time to 5 seconds in the WP Wall options. The Wall becomes a chat-box :)
= Is it possible to display a “Wall-Archive”-Page to show all comments?
Actually you will find WP Wall in your draft pages. Just edit it to your liking and - publish it! All comments will appear at the end of the page as usual.
= How do I add a border around the comment wall?
Add this to #wallcomments section of css file:
border: 1px solid #cccccc; padding 7px;
= How can I enable smilies?
WP Wall can show smilies using built in WordPress functionality if you enable it in your administration panel (Settings-> Writing-> Convert emoticons...). You can find more information about using smilies here http://codex.wordpress.org/Using_Smilies.
= How did you solve the problem with the commenters email address? usually you have to enter an email address, now doing that in a chat/shoutbox is cumbersome
The plugin does not require one to enter their email address.
