Validation errors

colspan - wrong number of columns (~line 104)
HTML5 doesn't like square braces in url so escaped it (~line 112)

corrected logic error whereby it was possible to generate an empty list of users (eg users exist but have contact method = none)

removed slightly misleading message "You have no pending messages" - number of messages already shown in title so this is redundant. PS HAVEN'T REMOVED FROM LANGUAGE FILES
