Weaver has asked me how to remove the irritating 'word verification' thing for people who want to comment on her posts (which has just become infuriating by adding an extra word which you can hardly read anyway, and often get wrong - especially after a couple of glasses of wine...) and so here is a step by step instruction for how to turn the bloody thing off, below.
I got so angry with it last night (after a few glasses of wine...) that I went on to a few people's sites and threatened never to comment again unless they disabled it, so it might be quite an incentive for you to leave it up after all, but that's up to you.
1: Go to DASHBOARD.
2: Click on SETTINGS.
2: Click on COMMENTS in the top bar.
3: Scroll down the page of options until you come across a bit called SHOW WORD VERIFICATION FOR COMMENTS? then click inside the little ring which is next to the 'NO' option, and the blue dot will appear inside the ring.
4: Go to the bottom of the page to where it asks you to SAVE SETTINGS and click there to save them. Job done.
Warning: You may receive more annoying comments from people like me if you opt out of the word verification hurdle, but I don't think it will increase your chances of someone hacking in to your blog - the word verification thing is designed to prevent automated entry by other computers (which is why they use wiggly writing that even humans have a hard job making out).
