It seems smarty tags don't work on custom blocks but you can apply them directly to the theme like this:
<{$xoops_uname}>
In some themes I have seen this:
<{if $xoops_isuser}> Hello <a href="<{$xoops_url}>/user.php"><{$xoops_uname}></a> <a href="<{$xoops_url}>/user.php">your
account </a> <{else}> <a href="<{$xoops_url}>/register.php">Register
now</a> on mysite.com! <{/if}> <span class="right"> <{if $xoops_isuser}>
<a href="<{$xoops_url}>/user.php?op=logout"></a> <{else}> <a href="<{$xoops_url}>/user.php">Login</a>
<{/if}> </span>
