If you have a PGP page, visitors may want to find trust paths

your key id :
<input type="text" name="FROM" size="14">
<input type="hidden" name="TO" value="********">
<input type="submit" name="PATHS" value="find trust paths to me">
<input type="reset" name="reset" value="reset">
</form>
and replace ******** with your long key-id ;
note the https.
