Brian,
No need to be like that. That's not cool. First, your post is vague, and to me, somewhat confusing. Are you talking about Register Plus, or are you talking about a different plugin (and then referring to Register Plus as an alternative)?
Second, regardless of which plugin your talking about, clearly, you're having a bad day, and I'm sorry for you. That being said, disliking the way someone writes his or her code, doesn't give anyone the right to howl at the moon and complain. The fact is, it's FREE. (if you're talking about Reg Plus). The author doesn't have to do anything. There are no guarantees.
I guess, what I'm saying is this. If you don't understand something, go to the forums to search and ask around. People are usually quite helpful. Don't come here to complain. That's not really beneficial to anyone. If that doesn't work, you can always create your own plugin.

Hope your plugin issues get worked out.
