Doubt about dynamicdrive

I was going to move this to feedback and announcements, but wasn't sure a person with only one post can see that forum. I think so, but I'm not sure.

Anyways, as to the legality of it, yes. As long as the script credit can be seen in the source code of the page using the script it's probably fine.

Technically speaking, this sort of thing is often done, but it can be tricky. Refer to the documentation for your particular wordpress package to see about the best ways of adding plugins. Many Dynamic Drive scripts have already been adapted as wordpress plugins.

Often you can just add the script "manually".
