The time delay in reposting is one of the controls that helps prevent multiple SPAM postings, and has been pretty effective - I know we still get some SPAMs, but they are single ones, not literally dozens at a time [I once had the pleasure of deleting some 200+ SPAMs one weekend, after a cyber attack on the IOSH Forums] The enforced delay between posts is about 5 minutes - but unfortunately the system only shows the seconds remaining, instead of minutes and seconds [Hope that makes sense], so one can get frustrated if one doesn't understand the 5 minute rule. As for the dyslexia problem and captcha - I also have similar difficulties with getting the letters/numbers right first [or second] time, but it is a small price to pay for helping to reduce SPAMs, as it discourages computer generated postings. Hope this explanation helps Mod 1
