I found Simple:Press to be the easiest forum to install on my neice's
site (which is based on the WP 2011 theme). Forums are good for
attracting people to come along / return to use your website.

Do a search for Simple:Press in the Plugin search box
                        > Install > Activate.

Simple:Press will set up its own webpage (so there's no need to
create a webpage for the forum, in advance).

Have a look at the available themes, & choose one to your liking …

Forum (on the Dashboard) > Themes > Available themes.
We chose “Berries 'n' cream” for the theme overlay ...

Removing the “Back to top” link in WordPress 2011 theme.

One problem I had with the Simple:Press plugin was that the
“Back to top” link in this theme, ended up above the forum interface,
instead of below it.

I couldn't find any reference to this link when I searched through
all the stylesheets in Editor, so I asked for help on this from the
WordPress Support team, one of whom advised inserting some text
into the main Stylesheet to over-ride the “Back to top” link ....

So here is how I went about doing this ...

First of all, you must download “Notepad++” (a free download)
onto your computer, and use this as your text editor.

You can copy the extra text (as I've shown in red below), paste it into
Notepad++, and then copy and paste the code into the main
Stylesheet.

Change the text colour to black, by the way, before inserting it into
the main Stylesheet.

To find the Stylesheet, click on Appearance > Editor.
Then scroll down the Stylesheet … look in the Content's main area
… carry on scrolling down, to see the page links as shown below.
Copy and paste the extra code into the Stylesheet (the code must be in
black and not in red).

/* =Content

----------------------------------------------- */

#main {

clear: both;

padding: 1.625em 0 0;

}

..............    (Don't add these blue dotted lines and my comment to the Stylesheet)

(Continue scrolling down the stylesheet)

..............

}

.page-link {

clear: both;

display: block;

margin: 0 0 1.625em;

}

.page-link a {

background: #eee;

color: #373737;

margin: 0;

padding: 2px 3px;

text-decoration: none;

}

.page-link a:hover {

background: #888;

color: #fff;

font-weight: bold;

}

.page-link span {

margin-right: 6px;

}

.back_to_top{display:none;

}

Press the blue “Update file” button, to finish.

Following all this, I then added the plugin “ToTop link”, which
works brilliantly.
