To join, you have to be a member of UCSL. To join, read the FAQ.

Once you are a member of UCSL, go to RingSurf and add your url in. This can be any site you run, but personal sites are preferred.

Once in, pick your code. You can have the plain text version, which looks like:

<< !! UCSL Member ?? >>

And is written like:
<center>
<a href="http://www.ringsurf.com/netring?ring=ucsl;id=***SITE ID***;action=prev"><<</a>
<a href="http://www.ringsurf.com/netring?ring=ucsl;action=list">!!</a>
<a href="http://www.dymphna.net/ucsl/">UCSL Member</a>
<a href="http://www.ringsurf.com/netring?ring=ucsl;action=rand">??</a>
<a href="http://www.ringsurf.com/netring?ring=ucsl;id=***SITE ID***;action=next">>></a>
</center>

Or save this image, and do this version:

<< !! ?? >>

And is written like:
<center>
<a href="http://www.dymphna.net/ucsl/"><img border=0 src="webringbutton1.gif" alt="UCSL Member" width=100 height=35></a>
<br>
<a href="http://www.ringsurf.com/netring?ring=ucsl;id=***SITE ID***;action=prev"><<</a>
<a href="http://www.ringsurf.com/netring?ring=ucsl;action=list">!!</a>
<a href="http://www.ringsurf.com/netring?ring=ucsl;action=rand">??</a>
<a href="http://www.ringsurf.com/netring?ring=ucsl;id=***SITE ID***;action=next">>></a>
</center>

Or if you want to be really complicated, use the imagemap version.

And is written like:
<center>
<IMG SRC="webringbutton2.gif" USEMAP="#ucslwebring" border=0 alt="UCSL Members" width=100 height=35>
<MAP NAME="ucslwebring">
<AREA SHAPE=RECT COORDS="1,1,57,34" HREF="http://www.dymphna.net/ucsl/">
