Dena the Captcha that was here previously prevented many people from joining the board, especially if they were from out of country. I luckily, had a comp that it worked with so I was registering people on the board at their request to get by it. That is why I asked Matthew to remove it so the people I knew were reading ITL could register en masse. Which they did. I know that some people over in LJ greated the news with joy because they had been trying and couldn't join either.
BUT there are some captcha programs that work well with simple machines boards and a couple of other solutions that have been found. I imagine it is just getting them set up and the time found to do it. I like my Friday ITL chapter and have that as a first priority for Matthew now he has cleaned the spammers out and shut the registration down.
It is soooooo good to come on the board and find your post and not have to search for it.
