I'm not sure why people have problems, wordpress runs about 30% of the websites on the Internet.
I do admit to having tightened down the process of getting posting rights, because of spammers. Since that seems to be working, I may be able to get rid of the recaptcha for logins, but keep it for new registrations.
I've done that and will monitor things to see if it causes any new problems and whether it helps people like Cass.
However, I'm frustrated with some other aspects of wordpress and may start checking out some other hosting software options.
