I don't know how relevant this is but I have noticed a few people entering the same post about 4 times, granted it is all unregistered members who maybe don't know any better or are simply spamming but it just seemed strange that it was 4 entries in each case. See the guestroom for a couple of examples. This may well be nothing but I just thought I would mention it.
p.s. a couple in 'Questions' and 'Problems'.
